Chapter 1. General Installation Considerations
|
|
|
|
Before starting the installation, first you need to know what do you
|
|
want to use PHP for. There are three main fields you can use PHP, as
|
|
described in the What can PHP do? section:
|
|
|
|
* Websites and web applications (server-side scripting)
|
|
* Command line scripting
|
|
* Desktop (GUI) applications
|
|
|
|
For the first and most common form, you need three things: PHP itself,
|
|
a web server and a web browser. You probably already have a web
|
|
browser, and depending on your operating system setup, you may also
|
|
have a web server (e.g. Apache on Linux and MacOS X; IIS on Windows).
|
|
You may also rent webspace at a company. This way, you don't need to
|
|
set up anything on your own, only write your PHP scripts, upload it to
|
|
the server you rent, and see the results in your browser.
|
|
|
|
In case of setting up the server and PHP on your own, you have two
|
|
choices for the method of connecting PHP to the server. For many
|
|
servers PHP has a direct module interface (also called SAPI). These
|
|
servers include Apache, Microsoft Internet Information Server, Netscape
|
|
and iPlanet servers. Many other servers have support for ISAPI, the
|
|
Microsoft module interface (OmniHTTPd for example). If PHP has no
|
|
module support for your web server, you can always use it as a CGI or
|
|
FastCGI processor. This means you set up your server to use the CGI
|
|
executable of PHP to process all PHP file requests on the server.
|
|
|
|
If you are also interested to use PHP for command line scripting (e.g.
|
|
write scripts autogenerating some images for you offline, or processing
|
|
text files depending on some arguments you pass to them), you always
|
|
need the command line executable. For more information, read the
|
|
section about writing command line PHP applications. In this case, you
|
|
need no server and no browser.
|
|
|
|
With PHP you can also write desktop GUI applications using the PHP-GTK
|
|
extension. This is a completely different approach than writing web
|
|
pages, as you do not output any HTML, but manage Windows and objects
|
|
within them. For more information about PHP-GTK, please visit the site
|
|
dedicated to this extension. PHP-GTK is not included in the official
|
|
PHP distribution.
|
|
|
|
From now on, this section deals with setting up PHP for web servers on
|
|
Unix and Windows with server module interfaces and CGI executables. You
|
|
will also find information on the command line executable in the
|
|
following sections.
|
|
|
|
PHP source code and binary distributions for Windows can be found at
|
|
http://www.php.net/downloads.php. We recommend you to choose a mirror
|
|
nearest to you for downloading the distributions.
|
|

|
Chapter 2. Installation on Windows systems
|
|
|
|
This section applies to Windows 98/Me and Windows NT/2000/XP/2003. PHP
|
|
will not work on 16 bit platforms such as Windows 3.1 and sometimes we
|
|
refer to the supported Windows platforms as Win32. Windows 95 is no
|
|
longer supported as of PHP 4.3.0.
|
|
|
|
There are two main ways to install PHP for Windows: either manually or
|
|
by using the installer.
|
|
|
|
If you have Microsoft Visual Studio, you can also build PHP from the
|
|
original source code.
|
|
|
|
Once you have PHP installed on your Windows system, you may also want
|
|
to load various extensions for added functionality.
|
|
|
|
Warning
|
|
|
|
There are several all-in-one installers over the Internet, but none of
|
|
those are endorsed by PHP.net, as we believe that the manual
|
|
installation is the best choice to have your system secure and
|
|
optimised.
|
|
__________________________________________________________________
|
|
|
|
Windows Installer (PHP 5.2 and later)
|
|
|
|
The Windows PHP installer for later versions of PHP is built using MSI
|
|
technology using the Wix Toolkit (http://wix.sourceforge.net/). It will
|
|
install and configure PHP and all the built-in and PECL extensions, as
|
|
well as configure many of the popular web servers such as IIS, Apache,
|
|
and Xitami.
|
|
|
|
First, install your selected HTTP (web) server on your system, and make
|
|
sure that it works. Then proceed with one of the following install
|
|
types.
|
|
__________________________________________________________________
|
|
|
|
Normal Install
|
|
|
|
Run the MSI installer and follow the instructions provided by the
|
|
installation wizard. You will be prompted to select the Web Server you
|
|
wish to configure first, along with any configuration details needed.
|
|
|
|
You will then be prompted to select which features and extensions you
|
|
wish to install and enable. By selecting "Will be installed on local
|
|
hard drive" in the drop-down menu for each item you can trigger whether
|
|
to install the feature or not. By selecting "Entire feature will be
|
|
installed on local hard drive", you will be able to install all
|
|
sub-features of the included feature ( for example by selecting this
|
|
options for the feature "PDO" you will install all PDO Drivers ).
|
|
|
|
Warning
|
|
|
|
It is not recommended to install all extensions by default, since many
|
|
other them require dependencies from outside PHP in order to function
|
|
properly. Instead, use the Installation Repair Mode that can be
|
|
triggered thru the 'Add/Remove Programs' control panel to enable or
|
|
disable extensions and features after installation.
|
|
|
|
The installer then sets up PHP to be used in Windows and the php.ini
|
|
file, and configures certain web servers to use PHP. The installer will
|
|
currently configure IIS (CGI mode only), Apache, Xitami, and Sambar
|
|
Server; if you are using a different web server you'll need to
|
|
configure it manually.
|
|
__________________________________________________________________
|
|
|
|
Silent Install
|
|
|
|
The installer also supports a silent mode, which is helpful for Systems
|
|
Administrators to deploy PHP easily. To use silent mode:
|
|
msiexec.exe /i php-VERSION-win32-install.msi /q
|
|
|
|
You can control the install directory by passing it as a parameter to
|
|
the install. For example, to install to e:\php:
|
|
msiexec.exe /i php-VERSION-win32-install.msi /q INSTALLDIR=e:\php
|
|
|
|
You can also use the same syntax to specify the Apache Configuration
|
|
Directory (APACHEDIR), the Sambar Server directory (SAMBARDIR), and the
|
|
Xitami Server directory (XITAMIDIR).
|
|
|
|
You can also specify what features to install. For example, to install
|
|
the mysqli extension and the CGI executable:
|
|
msiexec.exe /i php-VERSION-win32-install.msi /q ADDLOCAL=cgi,ext_php_mysqli
|
|
|
|
The current list of Features to install is as follows:
|
|
MainExecutable - php.exe executable
|
|
ScriptExecutable - php-win.exe executable
|
|
ext_php_* - the various extensions ( for example: ext_php_mysql for MySQL )
|
|
apache13 - Apache 1.3 module
|
|
apache20 - Apache 2.0 module
|
|
apache22 - Apache 2,2 module
|
|
apacheCGI - Apache CGI executable
|
|
iis4ISAPI - IIS ISAPI module
|
|
iis4CGI - IIS CGI executable
|
|
NSAPI - Sun/iPlanet/Netscape server module
|
|
Xitami - Xitami CGI executable
|
|
Sambar - Sambar Server ISAPI module
|
|
CGI - php-cgi.exe executable
|
|
PEAR - PEAR installer
|
|
Manual - PHP Manual in CHM Format

Windows Installer (PHP 5.1.0 and earlier)
|
|
|
|
The Windows PHP installer is available from the downloads page at
|
|
http://www.php.net/downloads.php. This installs the CGI version of PHP
|
|
and for IIS, PWS, and Xitami, it configures the web server as well. The
|
|
installer does not include any extra external PHP extensions
|
|
(php_*.dll) as you'll only find those in the Windows Zip Package and
|
|
PECL downloads.
|
|
|
|
Note: While the Windows installer is an easy way to make PHP work,
|
|
it is restricted in many aspects as, for example, the automatic
|
|
setup of extensions is not supported. Use of the installer isn't the
|
|
preferred method for installing PHP.
|
|
|
|
First, install your selected HTTP (web) server on your system, and make
|
|
sure that it works.
|
|
|
|
Run the executable installer and follow the instructions provided by
|
|
the installation wizard. Two types of installation are supported -
|
|
standard, which provides sensible defaults for all the settings it can,
|
|
and advanced, which asks questions as it goes along.
|
|
|
|
The installation wizard gathers enough information to set up the
|
|
php.ini file, and configure certain web servers to use PHP. One of the
|
|
web servers the PHP installer does not configure for is Apache, so
|
|
you'll need to configure it manually.
|
|
|
|
Once the installation has completed, the installer will inform you if
|
|
you need to restart your system, restart the server, or just start
|
|
using PHP.
|
|
|
|
Warning
|
|
|
|
Be aware, that this setup of PHP is not secure. If you would like to
|
|
have a secure PHP setup, you'd better go on the manual way, and set
|
|
every option carefully. This automatically working setup gives you an
|
|
instantly working PHP installation, but it is not meant to be used on
|
|
online servers.
|
|

|
Manual Installation Steps
|
|
|
|
This install guide will help you manually install and configure PHP
|
|
with a web server on Microsoft Windows. To get started you'll need to
|
|
download the zip binary distribution from the downloads page at
|
|
http://www.php.net/downloads.php.
|
|
|
|
Although there are many all-in-one installation kits, and we also
|
|
distribute a PHP installer for Microsoft Windows, we recommend you take
|
|
the time to setup PHP yourself as this will provide you with a better
|
|
understanding of the system, and enables you to install PHP extensions
|
|
easily when needed.
|
|
|
|
Upgrading from a previous PHP version: Previous editions of the
|
|
manual suggest moving various ini and DLL files into your SYSTEM
|
|
(i.e. C:\WINDOWS) folder and while this simplifies the installation
|
|
procedure it makes upgrading difficult. We advise you remove all of
|
|
these files (like php.ini and PHP related DLLs from the Windows
|
|
SYSTEM folder) before moving on with a new PHP installation. Be sure
|
|
to backup these files as you might break the entire system. The old
|
|
php.ini might be useful in setting up the new PHP as well. And as
|
|
you'll soon learn, the preferred method for installing PHP is to
|
|
keep all PHP related files in one directory and have this directory
|
|
available to your systems PATH.
|
|
|
|
MDAC requirements: If you use Microsoft Windows 98/NT4 download the
|
|
latest version of the Microsoft Data Access Components (MDAC) for
|
|
your platform. MDAC is available at http://msdn.microsoft.com/data/.
|
|
This requirement exists because ODBC is built into the distributed
|
|
Windows binaries.
|
|
|
|
The following steps should be completed on all installations before any
|
|
server specific instructions are performed:
|
|
|
|
Extract the distribution file into a directory of your choice. If you
|
|
are installing PHP 4, extract to C:\, as the zip file expands to a
|
|
foldername like php-4.3.7-Win32. If you are installing PHP 5, extract
|
|
to C:\php as the zip file doesn't expand as in PHP 4. You may choose a
|
|
different location but do not have spaces in the path (like C:\Program
|
|
Files\PHP) as some web servers will crash if you do.
|
|
|
|
The directory structure extracted from the zip is different for PHP
|
|
versions 4 and 5 and look like as follows:
|
|
|
|
Example 2-2. PHP 5 package structure
|
|
c:\php

|
|
|
|
Notice the differences and similarities. Both PHP 4 and PHP 5 have a
|
|
CGI executable, a CLI executable, and server modules, but they are
|
|
located in different folders and/or have different names. While PHP 4
|
|
packages have the server modules in the sapi folder, PHP 5
|
|
distributions have no such directory and instead they're in the PHP
|
|
folder root. The supporting DLLs for the PHP 5 extensions are also not
|
|
in a seperate directory.
|
|
|
|
Note: In PHP 4, you should move all files located in the dll and
|
|
sapi folders to the main folder (e.g. C:\php).
|
|
|
|
Here is a list of server modules shipped with PHP 5:
|
|
|
|
* sapi/php5apache2_2.dll - Apache 2.2.x module.
|
|
* sapi/php5apache.dll (php5apache.dll) - Apache 1.x module
|
|
* sapi/php5apache2.dll (php5apache2.dll) - - Apache 2.0.x module.
|
|
* sapi/php5isapi.dll - ISAPI Module for ISAPI compliant web servers
|
|
like IIS 5.0 or newer. However the FCGI SAPI is recommended with
|
|
IIS
|
|
* sapi/php5nsapi.dll (php5nsapi.dll) - Sun/iPlanet/Netscape server
|
|
module.
|
|
|
|
Server modules provide significantly better performance and additional
|
|
functionality compared to the CGI binary. The FastCGI is significantly
|
|
more stable and can be faster than the ISAPI module with IIS.
|
|
The CLI version is designed to let you use PHP for command line
|
|
scripting. More information about CLI is available in the chapter
|
|
about using PHP from the command line.
|
|
|
|
Warning
|
|
|
|
The SAPI modules have been significantly improved as of the 4.1
|
|
release, however, in older systems you may encounter server errors or
|
|
other server modules failing, such as ASP.
|
|
|
|
The CGI and CLI binaries, and the web server modules all require the
|
|
php5ts.dll file to be available to them. You have to make
|
|
sure that this file can be found by your PHP installation. The search
|
|
order for this DLL is as follows:
|
|
|
|
* The same directory from where php.exe is called, or in case you use
|
|
a SAPI module, the web server's directory (e.g. C:\Program
|
|
Files\Apache Group\Apache2\bin).
|
|
* Any directory in your Windows PATH environment variable.
|
|
|
|
To make php5ts.dll available you have three options: copy
|
|
the file to the Windows system directory, copy the file to the web
|
|
server's directory, or add your PHP directory, C:\php to the PATH. For
|
|
better maintenance, we advise you to follow the last option, add C:\php
|
|
to the PATH, because it will be simpler to upgrade PHP in the future.
|
|
Read more about how to add your PHP directory to PATH in the
|
|
corresponding FAQ entry (and then don't forget to restart the computer
|
|
- logoff isn't enough).
|
|
|
|
The next step is to set up a valid configuration file for PHP, php.ini.
|
|
There are two ini files distributed in the zip file, php.ini-development
|
|
and php.ini-production. We advise you to use php.ini-production,
|
|
because we optimized the default settings in this file for performance,
|
|
and security. Read this well documented file carefully because it has
|
|
changes from php.ini-production that will drastically affect your setup.
|
|
Some examples are display_errors being off and magic_quotes_gpc being off.
|
|
In addition to reading these, study the ini settings and set every
|
|
element manually yourself. If you would like to achieve the best
|
|
security, then this is the way for you, although PHP works fine with
|
|
these default ini files. Copy your chosen ini-file to a directory that
|
|
PHP is able to find and rename it to php.ini. PHP searches for php.ini
|
|
in the locations described in the Section called The configuration file
|
|
in Chapter 5 section.
|
|
|
|
If you are running Apache 2, the simpler option is to use the PHPIniDir
|
|
directive (read the installation on Apache 2 page), otherwise your best
|
|
option is to set the PHPRC environment variable. This process is
|
|
explained in the following FAQ entry.
|
|
|
|
Note: If you're using NTFS on Windows NT, 2000, XP or 2003, make
|
|
sure that the user running the web server has read permissions to
|
|
your php.ini (e.g. make it readable by Everyone).
|
|
|
|
The following steps are optional:
|
|
|
|
* Edit your new php.ini file. If you plan to use OmniHTTPd, do not
|
|
follow the next step. Set the doc_root to point to your web servers
|
|
document_root. For example:
|
|
|
|
doc_root = c:\inetpub\wwwroot // for IIS/PWS
|
|
|
|
doc_root = c:\apache\htdocs // for Apache
|
|
|
|
* Choose the extensions you would like to load when PHP starts. See
|
|
the section about Windows extensions, about how to set up one, and
|
|
what is already built in. Note that on a new installation it is
|
|
advisable to first get PHP working and tested without any
|
|
extensions before enabling them in php.ini.
|
|
* On PWS and IIS, you can set the browscap configuration setting to
|
|
point to: c:\windows\system\inetsrv\browscap.ini on Windows 9x/Me,
|
|
c:\winnt\system32\inetsrv\browscap.ini on NT/2000, and
|
|
c:\windows\system32\inetsrv\browscap.ini on XP. For an up-to-date
|
|
browscap.ini, read the following FAQ.
|
|
|
|
PHP is now setup on your system. The next step is to choose a web
|
|
server, and enable it to run PHP. Choose a web server from the table of
|
|
contents.
|
|

|
|
|
ActiveScript
|
|
|
|
This section contains notes specific to the ActiveScript installation.
|
|
|
|
ActiveScript is a Windows only SAPI that enables you to use PHP script
|
|
in any ActiveScript compliant host, like Windows Script Host,
|
|
ASP/ASP.NET, Windows Script Components or Microsoft Scriptlet control.
|
|
|
|
As of PHP 5.0.1, ActiveScript has been moved to the PECL repository.
|
|
The DLL for this PECL extension may be downloaded from either the PHP
|
|
Downloads page or from http://pecl4win.php.net/
|
|
|
|
Note: You should read the manual installation steps first!
|
|
|
|
After installing PHP, you should download the ActiveScript DLL
|
|
(php5activescript.dll) and place it in the main PHP folder (e.g.
|
|
C:\php).
|
|
|
|
After having all the files needed, you must register the DLL on your
|
|
system. To achieve this, open a Command Prompt window (located in the
|
|
Start Menu). Then go to your PHP directory by typing something like cd
|
|
C:\php. To register the DLL just type regsvr32 php5activescript.dll.
|
|
|
|
To test if ActiveScript is working, create a new file, named test.wsf
|
|
(the extension is very important) and type:
|
|
<job id="test">
|
|
|
|
<script language="PHPScript">
|
|
$WScript->Echo("Hello World!");
|
|
</script>
|
|
|
|
</job>
|
|
|
|
Save and double-click on the file. If you receive a little window
|
|
saying "Hello World!" you're done.
|
|
|
|
Note: In PHP 4, the engine was named 'ActivePHP', so if you are
|
|
using PHP 4, you should replace 'PHPScript' with 'ActivePHP' in the
|
|
above example.
|
|
|
|
Note: ActiveScript doesn't use the default php.ini file. Instead, it
|
|
will look only in the same directory as the .exe that caused it to
|
|
load. You should create php-activescript.ini and place it in that
|
|
folder, if you wish to load extensions, etc.

Microsoft IIS / PWS
|
|
|
|
This section contains notes and hints specific to IIS (Microsoft
|
|
Internet Information Server).
|
|
|
|
Warning
|
|
|
|
By using the CGI setup, your server is open to several possible
|
|
attacks. Please read our CGI security section to learn how to defend
|
|
yourself from those attacks.
|

__________________________________________________________________
|
|
|
|
General considerations for all installations of PHP with IIS or PWS
|
|
|
|
* First, read the Manual Installation Instructions. Do not skip this
|
|
step as it provides crucial information for installing PHP on
|
|
Windows.
|
|
* CGI users must set the cgi.force_redirect PHP directive to 0 inside
|
|
php.ini. Read the faq on cgi.force_redirect for important details.
|
|
Also, CGI users may want to set the cgi.redirect_status_env
|
|
directive. When using directives, be sure these directives aren't
|
|
commented out inside php.ini.
|
|
* The PHP 4 CGI is named php.exe while in PHP 5 it's php-cgi.exe. In
|
|
PHP 5, php.exe is the CLI, and not the CGI.
|
|
* Modify the Windows PATH environment variable to include the PHP
|
|
directory. This way the PHP DLL files and PHP executables can all
|
|
remain in the PHP directory without cluttering up the Windows
|
|
system directory. For more details, see the FAQ on Setting the
|
|
PATH.
|
|
* The IIS user (usually IUSR_MACHINENAME) needs permission to read
|
|
various files and directories, such as php.ini, docroot, and the
|
|
session tmp directory.
|
|
* Be sure the extension_dir and doc_root PHP directives are
|
|
appropriately set in php.ini. These directives depend on the system
|
|
that PHP is being installed on. In PHP 4, the extension_dir is
|
|
extensions while with PHP 5 it's ext. So, an example PHP 5
|
|
extensions_dir value is "c:\php\ext" and an example IIS doc_root
|
|
value is "c:\Inetpub\wwwroot".
|
|
* PHP extension DLL files, such as php_mysql.dll and php_curl.dll,
|
|
are found in the zip package of the PHP download (not the PHP
|
|
installer). In PHP 5, many extensions are part of PECL and can be
|
|
downloaded in the "Collection of PECL modules" package. Files such
|
|
as php_zip.dll and php_ssh2.dll. Download PHP files here.
|
|
* When defining the executable, the 'check that file exists' box may
|
|
also be checked. For a small performance penalty, the IIS (or PWS)
|
|
will check that the script file exists and sort out authentication
|
|
before firing up PHP. This means that the web server will provide
|
|
sensible 404 style error messages instead of CGI errors complaining
|
|
that PHP did not output any data.
|
|
__________________________________________________________________
|
|
|
|
Windows NT/200x/XP and IIS 4 or newer
|
|
|
|
PHP may be installed as a CGI binary, or with the ISAPI module. In
|
|
either case, you need to start the Microsoft Management Console (may
|
|
appear as 'Internet Services Manager', either in your Windows NT 4.0
|
|
Option Pack branch or the Control Panel=>Administrative Tools under
|
|
Windows 2000/XP). Then right click on your Web server node (this will
|
|
most probably appear as 'Default Web Server'), and select 'Properties'.
|
|
|
|
If you want to use the CGI binary, do the following:
|
|
|
|
* Under 'Home Directory', 'Virtual Directory', or 'Directory', do the
|
|
following:
|
|
* Change the Execute Permissions to 'Scripts only'
|
|
* Click on the 'Configuration' button, and choose the Application
|
|
Mappings tab. Click Add and set the Executable path to the
|
|
appropriate CGI file. An example PHP 5 value is: C:\php\php-cgi.exe
|
|
Supply .php as the extension. Leave 'Method exclusions' blank, and
|
|
check the 'Script engine' checkbox. Now, click OK a few times.
|
|
* Set up the appropriate security. (This is done in Internet Service
|
|
Manager), and if your NT Server uses NTFS file system, add execute
|
|
rights for I_USR_ to the directory that contains php.exe /
|
|
php-cgi.exe.
|
|
|
|
To use the ISAPI module, do the following:
|
|
|
|
* If you don't want to perform HTTP Authentication using PHP, you can
|
|
(and should) skip this step. Under ISAPI Filters, add a new ISAPI
|
|
filter. Use PHP as the filter name, and supply a path to the
|
|
php5isapi.dll.
|
|
* Under 'Home Directory', 'Virtual Directory', or 'Directory', do the
|
|
following:
|
|
* Change the Execute Permissions to 'Scripts only'
|
|
* Click on the 'Configuration' button, and choose the Application
|
|
Mappings tab. Click Add and set the Executable path to the
|
|
appropriate ISAPI DLL. An example PHP 5 value is:
|
|
C:\php\php5isapi.dll Supply .php as the extension. Leave 'Method
|
|
exclusions' blank, and check the 'Script engine' checkbox. Now,
|
|
click OK a few times.
|
|
* Stop IIS completely (NET STOP iisadmin)
|
|
* Start IIS again (NET START w3svc)
|
|
|
|
With IIS 6 (2003 Server), open up the IIS Manager, go to Web Service
|
|
Extensions, choose "Add a new Web service extension", enter in a name
|
|
such as PHP, choose the Add button and for the value browse to either
|
|
the ISAPI file (php5isapi.dll) or CGI (php.exe or
|
|
php-cgi.exe) then check "Set extension status to Allowed" and click OK.
|
|
|
|
In order to use index.php as a default content page, do the following:
|
|
From within the Documents tab, choose Add. Type in index.php and click
|
|
OK. Adjust the order by choosing Move Up or Move Down. This is similar
|
|
to setting DirectoryIndex with Apache.
|
|
|
|
The steps above must be repeated for each extension that is to be
|
|
associated with PHP scripts. .php is the most common although .php3 may
|
|
be required for legacy applications.
|
|
|
|
If you experience 100% CPU usage after some time, turn off the IIS
|
|
setting Cache ISAPI Application.

Apache 1.3.x on Microsoft Windows
|
|
|
|
This section contains notes and hints specific to Apache 1.3.x installs
|
|
of PHP on Microsoft Windows systems. There are also instructions and
|
|
notes for Apache 2 on a separate page.
|
|
|
|
Note: Please read the manual installation steps first!
|
|
|
|
There are two ways to set up PHP to work with Apache 1.3.x on Windows.
|
|
One is to use the CGI binary (php.exe for PHP 4 and php-cgi.exe for PHP
|
|
5), the other is to use the Apache Module DLL. In either case you need
|
|
to edit your httpd.conf to configure Apache to work with PHP, and then
|
|
restart the server.
|
|
|
|
It is worth noting here that now the SAPI module has been made more
|
|
stable under Windows, we recommend it's use above the CGI binary, since
|
|
it is more transparent and secure.
|
|
|
|
Although there can be a few variations of configuring PHP under Apache,
|
|
these are simple enough to be used by the newcomer. Please consult the
|
|
Apache Documentation for further configuration directives.
|
|
|
|
After changing the configuration file, remember to restart the server,
|
|
for example, NET STOP APACHE followed by NET START APACHE, if you run
|
|
Apache as a Windows Service, or use your regular shortcuts.
|
|
|
|
Note: Remember that when adding path values in the Apache
|
|
configuration files on Windows, all backslashes such as
|
|
c:\directory\file.ext must be converted to forward slashes, as
|
|
c:/directory/file.ext. A trailing slash may also be necessary for
|
|
directories.
|
|
__________________________________________________________________
|
|
|
|
Installing as an Apache module
|
|
|
|
You should add the following lines to your Apache httpd.conf file:
|
|
|
|
Example 2-3. PHP as an Apache 1.3.x module
|
|
|
|
This assumes PHP is installed to c:\php. Adjust the path if this is not
|
|
the case.
|
|
|
|
For PHP 5:
|
|
# Add to the end of the LoadModule section
|
|
LoadModule php5_module "C:/php/php5apache.dll"
|
|
|
|
# Add to the end of the AddModule section
|
|
AddModule mod_php5.c
|
|
|
|
For both:
|
|
# Add this line inside the <IfModule mod_mime.c> conditional brace
|
|
AddType application/x-httpd-php .php
|
|
|
|
# For syntax highlighted .phps files, also add
|
|
AddType application/x-httpd-php-source .phps
|
|
__________________________________________________________________
|
|
|
|
Installing as a CGI binary
|
|
|
|
If you unzipped the PHP package to C:\php\ as described in the Manual
|
|
Installation Steps section, you need to insert these lines to your
|
|
Apache configuration file to set up the CGI binary:
|
|
|
|
Example 2-4. PHP and Apache 1.3.x as CGI
|
|
ScriptAlias /php/ "c:/php/"
|
|
AddType application/x-httpd-php .php
|
|
|
|
# For PHP 4
|
|
Action application/x-httpd-php "/php/php.exe"
|
|
|
|
# For PHP 5
|
|
Action application/x-httpd-php "/php/php-cgi.exe"
|
|
|
|
# specify the directory where php.ini is
|
|
SetEnv PHPRC C:/php
|
|
|
|
Note that the second line in the list above can be found in the actual
|
|
versions of httpd.conf, but it is commented out. Remember also to
|
|
substitute the c:/php/ for your actual path to PHP.
|
|
|
|
Warning
|
|
|
|
By using the CGI setup, your server is open to several possible
|
|
attacks. Please read our CGI security section to learn how to defend
|
|
yourself from those attacks.
|
|
|
|
If you would like to present PHP source files syntax highlighted, there
|
|
is no such convenient option as with the module version of PHP. If you
|
|
chose to configure Apache to use PHP as a CGI binary, you will need to
|
|
use the highlight_file() function. To do this simply create a PHP
|
|
script file and add this code: <?php
|
|
highlight_file('some_php_script.php'); ?>.

Apache 2.0.x on Microsoft Windows
|
|
|
|
This section contains notes and hints specific to Apache 2.0.x installs
|
|
of PHP on Microsoft Windows systems. We also have instructions and
|
|
notes for Apache 1.3.x users on a separate page.
|
|
|
|
Note: You should read the manual installation steps first!
|
|
|
|
Apache 2.2.x Support: Users of Apache 2.2.x may use the
|
|
documentation below except the appropriate DLL file is named
|
|
php5apache2_2.dll and it only exists as of PHP 5.2.0. See also
|
|
http://snaps.php.net/
|
|
|
|
Warning
|
|
|
|
We do not recommend using a threaded MPM in production with Apache2.
|
|
Use the prefork MPM instead, or use Apache1. For information on why,
|
|
read the related FAQ entry on using Apache2 with a threaded MPM
|
|
|
|
You are highly encouraged to take a look at the Apache Documentation to
|
|
get a basic understanding of the Apache 2.0.x Server. Also consider to
|
|
read the Windows specific notes for Apache 2.0.x before reading on
|
|
here.
|
|
|
|
PHP and Apache 2.0.x compatibility notes: The following versions of
|
|
PHP are known to work with the most recent version of Apache 2.0.x:
|
|
|
|
* PHP 4.3.0 or later available at http://www.php.net/downloads.php.
|
|
* the latest stable development version. Get the source code
|
|
http://snaps.php.net/php5-latest.tar.gz or download binaries for
|
|
Windows http://snaps.php.net/win32/php5-win32-latest.zip.
|
|
* a prerelease version downloadable from http://qa.php.net/.
|
|
* you have always the option to obtain PHP through SVN.
|
|
|
|
These versions of PHP are compatible to Apache 2.0.40 and later.
|
|
|
|
Apache 2.0 SAPI-support started with PHP 4.2.0. PHP 4.2.3 works with
|
|
Apache 2.0.39, don't use any other version of Apache with PHP 4.2.3.
|
|
However, the recommended setup is to use PHP 4.3.0 or later with the
|
|
most recent version of Apache2.
|
|
|
|
All mentioned versions of PHP will work still with Apache 1.3.x.
|
|
|
|
Warning
|
|
|
|
Apache 2.0.x is designed to run on Windows NT 4.0, Windows 2000 or
|
|
Windows XP. At this time, support for Windows 9x is incomplete. Apache
|
|
2.0.x is not expected to work on those platforms at this time.
|
|
|
|
Download the most recent version of Apache 2.0.x and a fitting PHP
|
|
version. Follow the Manual Installation Steps and come back to go on
|
|
with the integration of PHP and Apache.
|
|
|
|
There are two ways to set up PHP to work with Apache 2.0.x on Windows.
|
|
One is to use the CGI binary the other is to use the Apache module DLL.
|
|
In either case you need to edit your httpd.conf to configure Apache to
|
|
work with PHP and then restart the server.
|
|
|
|
Note: Remember that when adding path values in the Apache
|
|
configuration files on Windows, all backslashes such as
|
|
c:\directory\file.ext must be converted to forward slashes, as
|
|
c:/directory/file.ext. A trailing slash may also be necessary for
|
|
directories.

Installing as a CGI binary
|
|
|
|
You need to insert these three lines to your Apache httpd.conf

configuration file to set up the CGI binary:
|
|
|
|
Example 2-5. PHP and Apache 2.0 as CGI
|
|
ScriptAlias /php/ "c:/php/"
|
|
AddType application/x-httpd-php .php
|
|
|
|
# For PHP 4
|
|
Action application/x-httpd-php "/php/php.exe"
|
|
|
|
# For PHP 5
|
|
Action application/x-httpd-php "/php/php-cgi.exe"
|
|
|
|
Warning
|

|
|
|
|
Installing as an Apache module
|
|
|
|
You need to insert these two lines to your Apache httpd.conf
|
|
configuration file to set up the PHP module for Apache 2.0:
|
|
|
|
Example 2-6. PHP and Apache 2.0 as Module
|
|
|
|
# For PHP 5 do something like this:
|
|
LoadModule php5_module "c:/php/php5apache2.dll"
|
|
AddType application/x-httpd-php .php
|
|
|
|
# configure the path to php.ini
|
|
PHPIniDir "C:/php"
|
|
|
|
Note: Remember to substitute your actual path to PHP for the c:/php/
|
|
in the above examples. Take care to use either
|
|
php5apache2.dll in your LoadModule directive and not php5apache.dll
|
|
as the latter ones are designed to run with Apache 1.3.x.
|
|
|
|
Note: If you want to use content negotiation, read related FAQ.
|
|
|
|
Warning
|
|
|
|
Don't mix up your installation with DLL files from different PHP
|
|
versions. You have the only choice to use the DLL's and extensions that
|
|
ship with your downloaded PHP version.

Sun, iPlanet and Netscape servers on Microsoft Windows
|
|
|
|
This section contains notes and hints specific to Sun Java System Web
|
|
Server, Sun ONE Web Server, iPlanet and Netscape server installs of PHP
|
|
on Windows.
|
|
|
|
From PHP 4.3.3 on you can use PHP scripts with the NSAPI module to
|
|
generate custom directory listings and error pages. Additional
|
|
functions for Apache compatibility are also available. For support in
|
|
current web servers read the note about subrequests.

|
CGI setup on Sun, iPlanet and Netscape servers
|
|
|
|
To install PHP as a CGI handler, do the following:
|
|
|
|
* Copy php5ts.dll to your systemroot (the directory where you
|
|
installed Windows)
|
|
* Make a file association from the command line. Type the following
|
|
two lines:
|
|
|
|
assoc .php=PHPScript
|
|
ftype PHPScript=c:\php\php.exe %1 %*
|
|
|
|
* In the Netscape Enterprise Administration Server create a dummy
|
|
shellcgi directory and remove it just after (this step creates 5
|
|
important lines in obj.conf and allow the web server to handle
|
|
shellcgi scripts).
|
|
* In the Netscape Enterprise Administration Server create a new mime
|
|
type (Category: type, Content-Type: magnus-internal/shellcgi, File
|
|
Suffix:php).
|
|
* Do it for each web server instance you want PHP to run
|
|
|
|

|
|
|
NSAPI setup on Sun, iPlanet and Netscape servers
|
|
|
|
To install PHP with NSAPI, do the following:
|
|
|
|
* Copy php5ts.dll to your systemroot (the directory where you
|
|
installed Windows)
|
|
* Make a file association from the command line. Type the following
|
|
two lines:
|
|
|
|
assoc .php=PHPScript
|
|
ftype PHPScript=c:\php\php.exe %1 %*
|
|
|
|
* In the Netscape Enterprise Administration Server create a new mime
|
|
type (Category: type, Content-Type: magnus-internal/x-httpd-php,
|
|
File Suffix: php).
|
|
* Edit magnus.conf (for servers >= 6) or obj.conf (for servers < 6)
|
|
and add the following: You should place the lines after mime types
|
|
init.
|
|
|
|
Init fn="load-modules" funcs="php5_init,php5_execute,php5_auth_trans" shlib="c:/
|
|
php/sapi/php5nsapi.dll"
|
|
Init fn="php5_init" LateInit="yes" errorString="Failed to initialise PHP!" [php_
|
|
ini="c:/path/to/php.ini"]
|
|
|
|
The php_ini parameter is optional but with it you
|
|
can place your php.ini in your web server configuration directory.
|
|
* Configure the default object in obj.conf (for virtual server
|
|
classes [Sun Web Server 6.0+] in their vserver.obj.conf): In the
|
|
<Object name="default"> section, place this line necessarily after
|
|
all 'ObjectType' and before all 'AddLog' lines:
|
|
|
|
Service fn="php5_execute" type="magnus-internal/x-httpd-php" [inikey=value inike
|
|
y=value ...]
|
|
|
|
As additional parameters you can add some special
|
|
php.ini-values, for example you can set a
|
|
docroot="/path/to/docroot" specific to the context php5_execute is
|
|
called. For boolean ini-keys please use 0/1 as value, not
|
|
"On","Off",... (this will not work correctly), e.g.
|
|
zlib.output_compression=1 instead of zlib.output_compression="On"
|
|
* This is only needed if you want to configure a directory that only
|
|
consists of PHP scripts (same like a cgi-bin directory):
|
|
|
|
<Object name="x-httpd-php">
|
|
ObjectType fn="force-type" type="magnus-internal/x-httpd-php"
|
|
Service fn=php5_execute [inikey=value inikey=value ...]
|
|
</Object>
|
|
|
|
After that you can configure a directory in the Administration
|
|
server and assign it the style x-httpd-php. All files in it will
|
|
get executed as PHP. This is nice to hide PHP usage by renaming
|
|
files to .html.
|
|
* Restart your web service and apply changes
|
|
* Do it for each web server instance you want PHP to run
|
|
|
|
Note: More details about setting up PHP as an NSAPI filter can be
|
|
found here: http://benoit.noss.free.fr/php/install-php4.html
|
|
|
|
Note: The stacksize that PHP uses depends on the configuration of
|
|
the web server. If you get crashes with very large PHP scripts, it
|
|
is recommended to raise it with the Admin Server (in the section
|
|
"MAGNUS EDITOR").
|
|
__________________________________________________________________
|
|
|
|
CGI environment and recommended modifications in php.ini
|
|
|
|
Important when writing PHP scripts is the fact that Sun JSWS/Sun ONE
|
|
WS/iPlanet/Netscape is a multithreaded web server. Because of that all
|
|
requests are running in the same process space (the space of the web
|
|
server itself) and this space has only one environment. If you want to
|
|
get CGI variables like PATH_INFO, HTTP_HOST etc. it is not the correct
|
|
way to try this in the old PHP 3.x way with getenv() or a similar way
|
|
(register globals to environment, $_ENV). You would only get the
|
|
environment of the running web server without any valid CGI variables!
|
|
|
|
Note: Why are there (invalid) CGI variables in the environment?
|
|
|
|
Answer: This is because you started the web server process from the
|
|
admin server which runs the startup script of the web server, you
|
|
wanted to start, as a CGI script (a CGI script inside of the admin
|
|
server!). This is why the environment of the started web server has
|
|
some CGI environment variables in it. You can test this by starting
|
|
the web server not from the administration server. Use the command
|
|
line as root user and start it manually - you will see there are no
|
|
CGI-like environment variables.
|
|
|
|
Simply change your scripts to get CGI variables in the correct way for
|
|
PHP 5.x by using the superglobal $_SERVER. If you have older scripts
|
|
which use $HTTP_HOST, etc., you should turn on register_globals in
|
|
php.ini and change the variable order too (important: remove "E" from
|
|
it, because you do not need the environment here):
|
|
variables_order = "GPCS"
|
|
register_globals = On
|
|
__________________________________________________________________
|
|
|
|
Special use for error pages or self-made directory listings (PHP >= 4.3.3)
|
|
|
|
You can use PHP to generate the error pages for "404 Not Found" or
|
|
similar. Add the following line to the object in obj.conf for every
|
|
error page you want to overwrite:
|
|
Error fn="php5_execute" code=XXX script="/path/to/script.php" [inikey=value inik
|
|
ey=value...]
|
|
|
|
where XXX is the HTTP error code. Please delete any other Error
|
|
directives which could interfere with yours. If you want to place a
|
|
page for all errors that could exist, leave the code parameter out.
|
|
Your script can get the HTTP status code with $_SERVER['ERROR_TYPE'].
|
|
|
|
Another possibility is to generate self-made directory listings. Just
|
|
create a PHP script which displays a directory listing and replace the
|
|
corresponding default Service line for type="magnus-internal/directory"
|
|
in obj.conf with the following:
|
|
Service fn="php5_execute" type="magnus-internal/directory" script="/path/to/scri
|
|
pt.php" [inikey=value inikey=value...]
|
|
|
|
For both error and directory listing pages the original URI and
|
|
translated URI are in the variables $_SERVER['PATH_INFO'] and
|
|
$_SERVER['PATH_TRANSLATED'].

|
|
Note about nsapi_virtual() and subrequests (PHP >= 4.3.3)
|
|
|
|
The NSAPI module now supports the nsapi_virtual() function (alias:
|
|
virtual()) to make subrequests on the web server and insert the result
|
|
in the web page. The problem is, that this function uses some
|
|
undocumented features from the NSAPI library.
|
|
|
|
Under Unix this is not a problem, because the module automatically
|
|
looks for the needed functions and uses them if available. If not,
|
|
nsapi_virtual() is disabled.
|
|
|
|
Under Windows limitations in the DLL handling need the use of a
|
|
automatic detection of the most recent ns-httpdXX.dll file. This is
|
|
tested for servers till version 6.1. If a newer version of the Sun
|
|
server is used, the detection fails and nsapi_virtual() is disabled.
|
|
|
|
If this is the case, try the following: Add the following parameter to
|
|
php5_init in magnus.conf/obj.conf:
|
|
Init fn=php5_init ... server_lib="ns-httpdXX.dll"
|
|
|
|
where XX is the correct DLL version number. To get it, look in the
|
|
server-root for the correct DLL name. The DLL with the biggest filesize
|
|
is the right one.
|
|
|
|
You can check the status by using the phpinfo() function.
|
|
|
|
Note: But be warned: Support for nsapi_virtual() is EXPERIMENTAL!!!

|
Installation of extensions on Windows
|
|
|
|
After installing PHP and a web server on Windows, you will probably
|
|
want to install some extensions for added functionality. You can choose
|
|
which extensions you would like to load when PHP starts by modifying
|
|
your php.ini. You can also load a module dynamically in your script
|
|
using dl().
|
|
|
|
The DLLs for PHP extensions are prefixed with php_.
|
|
|
|
Many extensions are built into the Windows version of PHP. This means
|
|
additional DLL files, and the extension directive, are not used to load
|
|
these extensions. The Windows PHP Extensions table lists extensions
|
|
that require, or used to require, additional PHP DLL files. Here's a
|
|
list of built in extensions:
|
|
|
|
In PHP 5 (updated PHP 5.0.4), the following changes exist. Built in:
|
|
DOM, LibXML, Iconv, SimpleXML, SPL and SQLite. And the following are no
|
|
longer built in: MySQL and Overload.
|
|
|
|
The default location PHP searches for extensions is C:\php5 in PHP 5.
|
|
To change this setting to reflect your setup of PHP edit your php.ini
|
|
file:
|
|
|
|
* You will need to change the extension_dir setting to point to the
|
|
directory where your extensions lives, or where you have placed
|
|
your php_*.dll files. For example:
|
|
|
|
extension_dir = C:\php\extensions
|
|
|
|
* Enable the extension(s) in php.ini you want to use by uncommenting
|
|
the extension=php_*.dll lines in php.ini. This is done by deleting
|
|
the leading ; from the extension you want to load.
|
|
|
|
Example 2-8. Enable Bzip2 extension for PHP-Windows
|
|
// change the following line from ...
|
|
;extension=php_bz2.dll
|
|
|
|
// ... to
|
|
extension=php_bz2.dll
|
|
|
|
* Some of the extensions need extra DLLs to work. Couple of them can
|
|
be found in the distribution package, in in the main folder in PHP 5,
|
|
but some, for example Oracle (php_oci8.dll) require DLLs which are
|
|
not bundled with the distribution package.
|
|
* Some of these DLLs are not bundled with the PHP distribution. See
|
|
each extensions documentation page for details. Also, read the
|
|
manual section titled Installation of PECL extensions for details
|
|
on PECL. An increasingly large number of PHP extensions are found
|
|
in PECL, and these extensions require a separate download.
|
|
|
|
Note: If you are running a server module version of PHP remember to
|
|
restart your web server to reflect your changes to php.ini.
|
|
|
|
The following table describes some of the extensions available and
|
|
required additional dlls.

Chapter 3. Installation of PECL extensions
|
|
|
|
Introduction to PECL Installations
|
|
|
|
PECL is a repository of PHP extensions that are made available to you
|
|
via the PEAR packaging system. This section of the manual is intended
|
|
to demonstrate how to obtain and install PECL extensions.
|
|
|
|
These instructions assume /your/phpsrcdir/ is the path to the PHP
|
|
source distribution, and that extname is the name of the PECL
|
|
extension. Adjust accordingly. These instructions also assume a
|
|
familiarity with the pear command. The information in the PEAR manual
|
|
for the pear command also applies to the pecl command.
|
|
|
|
To be useful, a shared extension must be built, installed, and loaded.
|
|
The methods described below provide you with various instructions on
|
|
how to build and install the extensions, but they do not automatically
|
|
load them. Extensions can be loaded by adding an extension directive.
|
|
To this php.ini file, or through the use of the dl() function.
|
|
|
|
When building PHP modules, it's important to have known-good versions
|
|
of the required tools (autoconf, automake, libtool, etc.) See the
|
|
SVN Instructions for details on the required tools, and required
|
|
versions.
|
|
__________________________________________________________________
|
|
|
|
Downloading PECL extensions
|
|
|
|
There are several options for downloading PECL extensions, such as:
|
|
|
|
* http://pecl.php.net
|
|
The PECL web site contains information about the different
|
|
extensions that are offered by the PHP Development Team. The
|
|
information available here includes: ChangeLog, release notes,
|
|
requirements and other similar details.
|
|
* pecl download extname
|
|
PECL extensions that have releases listed on the PECL web site are
|
|
available for download and installation using the pecl command.
|
|
Specific revisions may also be specified.
|
|
* SVN
|
|
Most PECL extensions also reside in SVN. A web-based view may be
|
|
seen at http://svn.php.net/pecl/. To download straight from SVN,
|
|
the following sequence of commands may be used.
|
|
|
|
$ svn co http://svn.php.net/repository/pecl/<extname>/trunk
|
|
|
|
* Windows downloads
|
|
Windows users may find compiled PECL binaries by downloading the
|
|
Collection of PECL modules from the PHP Downloads page, or by
|
|
retrieving a PECL Snapshot or an extension DLL on PECL4WIN. To
|
|
compile PHP under Windows, read the appropriate chapter.
|
|
__________________________________________________________________
|
|
|
|
PECL for Windows users
|
|
|
|
As with any other PHP extension DLL, installation is as simple as
|
|
copying the PECL extension DLLs into the extension_dir folder and
|
|
loading them from php.ini. For example, add the following line to your
|
|
php.ini:
|
|
|
|
extension=php_extname.dll
|
|
|
|
After doing this, restart the web server.
|
|
__________________________________________________________________
|
|
|
|
Compiling shared PECL extensions with the pecl command
|
|
|
|
PECL makes it easy to create shared PHP extensions. Using the pecl
|
|
command, do the following:
|
|
|
|
$ pecl install extname
|
|
|
|
This will download the source for extname, compile, and install
|
|
extname.so into your extension_dir. extname.so may then be loaded via
|
|
php.ini
|
|
|
|
By default, the pecl command will not install packages that are marked
|
|
with the alpha or beta state. If no stable packages are available, you
|
|
may install a beta package using the following command:
|
|
|
|
$ pecl install extname-beta
|
|
|
|
You may also install a specific version using this variant:
|
|
|
|
$ pecl install extname-0.1
|
|
__________________________________________________________________
|
|
|
|
Compiling shared PECL extensions with phpize
|
|
|
|
Sometimes, using the pecl installer is not an option. This could be
|
|
because you're behind a firewall, or it could be because the extension
|
|
you want to install is not available as a PECL compatible package, such
|
|
as unreleased extensions from SVN. If you need to build such an
|
|
extension, you can use the lower-level build tools to perform the build
|
|
manually.
|
|
|
|
The phpize command is used to prepare the build environment for a PHP
|
|
extension. In the following sample, the sources for an extension are in
|
|
a directory named extname:
|
|
|
|
$ cd extname
|
|
$ phpize
|
|
$ ./configure
|
|
$ make
|
|
# make install
|
|
|
|
A successful install will have created extname.so and put it into the
|
|
PHP extensions directory. You'll need to and adjust php.ini and add an
|
|
extension=extname.so line before you can use the extension.
|
|
|
|
If the system is missing the phpize command, and precompiled packages
|
|
(like RPM's) are used, be sure to also install the appropriate devel
|
|
version of the PHP package as they often include the phpize command
|
|
along with the appropriate header files to build PHP and its
|
|
extensions.
|
|
|
|
Execute phpize --help to display additional usage information.
|
|
__________________________________________________________________
|
|
|
|
Compiling PECL extensions statically into PHP
|
|
|
|
You might find that you need to build a PECL extension statically into
|
|
your PHP binary. To do this, you'll need to place the extension source
|
|
under the php-src/ext/ directory and tell the PHP build system to
|
|
regenerate its configure script.
|
|
|
|
$ cd /your/phpsrcdir/ext
|
|
$ pecl download extname
|
|
$ gzip -d < extname.tgz | tar -xvf -
|
|
$ mv extname-x.x.x extname
|
|
|
|
This will result in the following directory:
|
|
|
|
/your/phpsrcdir/ext/extname
|
|
|
|
From here, force PHP to rebuild the configure script, and then build
|
|
PHP as normal:
|
|
|
|
$ cd /your/phpsrcdir
|
|
$ rm configure
|
|
$ ./buildconf --force
|
|
$ ./configure --help
|
|
$ ./configure --with-extname --enable-someotherext --with-foobar
|
|
$ make
|
|
$ make install
|
|
|
|
Note: To run the 'buildconf' script you need autoconf 2.13 and
|
|
automake 1.4+ (newer versions of autoconf may work, but are not
|
|
supported).
|
|
|
|
Whether --enable-extname or --with-extname is used depends on the
|
|
extension. Typically an extension that does not require external
|
|
libraries uses --enable. To be sure, run the following after buildconf:
|
|
|
|
$ ./configure --help | grep extname
|
|

|
Other problems
|
|
|
|
If you are still stuck, someone on the PHP installation mailing list
|
|
may be able to help you. You should check out the archive first, in
|
|
case someone already answered someone else who had the same problem as
|
|
you. The archives are available from the support page on
|
|
http://www.php.net/support.php. To subscribe to the PHP installation
|
|
mailing list, send an empty mail to
|
|
php-install-subscribe@lists.php.net. The mailing list address is
|
|
php-install@lists.php.net.
|
|
|
|
If you want to get help on the mailing list, please try to be precise
|
|
and give the necessary details about your environment (which operating
|
|
system, what PHP version, what web server, if you are running PHP as
|
|
CGI or a server module, safe mode, etc...), and preferably enough code
|
|
to make others able to reproduce and test your problem.

Bug reports
|
|
|
|
If you think you have found a bug in PHP, please report it. The PHP
|
|
developers probably don't know about it, and unless you report it,
|
|
chances are it won't be fixed. You can report bugs using the
|
|
bug-tracking system at http://bugs.php.net/. Please do not send bug
|
|
reports in mailing list or personal letters. The bug system is also
|
|
suitable to submit feature requests.
|
|
|
|
Read the How to report a bug document before submitting any bug
|
|
reports!

Chapter 5. Runtime Configuration
|
|
|
|
The configuration file
|
|
|
|
The configuration file (called php3.ini in PHP 3, and simply php.ini as
|
|
of PHP 4) is read when PHP starts up. For the server module versions of
|
|
PHP, this happens only once when the web server is started. For the CGI
|
|
and CLI version, it happens on every invocation.
|
|
|
|
php.ini is searched in these locations (in order):
|
|
|
|
* SAPI module specific location (PHPIniDir directive in Apache 2, -c
|
|
command line option in CGI and CLI, php_ini parameter in NSAPI,
|
|
PHP_INI_PATH environment variable in THTTPD)
|
|
* The PHPRC environment variable. Before PHP 5.2.0 this was checked
|
|
after the registry key mentioned below.
|
|
* As of PHP 5.2.0, the following registry locations are searched in
|
|
order: HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x.y.z\IniFilePath,
|
|
HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x.y\IniFilePath and
|
|
HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x\IniFilePath, where x, y and z
|
|
mean the PHP major, minor and release versions.
|
|
* HKEY_LOCAL_MACHINE\SOFTWARE\PHP\IniFilePath (Windows Registry
|
|
location)
|
|
* Current working directory (except CLI)
|
|
* The web server's directory (for SAPI modules), or directory of PHP
|
|
(otherwise in Windows)
|
|
* Windows directory (C:\windows or C:\winnt) (for Windows), or
|
|
--with-config-file-path compile time option
|
|
|
|
If php-SAPI.ini exists (where SAPI is used SAPI, so the filename is
|
|
e.g. php-cli.ini or php-apache.ini), it's used instead of php.ini. SAPI
|
|
name can be determined by php_sapi_name().
|
|
|
|
Note: The Apache web server changes the directory to root at startup
|
|
causing PHP to attempt to read php.ini from the root filesystem if
|
|
it exists.
|
|
|
|
The php.ini directives handled by extensions are documented
|
|
respectively on the pages of the extensions themselves. The list of the
|
|
core directives is available in the appendix. Probably not all PHP
|
|
directives are documented in the manual though. For a complete list of
|
|
directives available in your PHP version, please read your well
|
|
commented php.ini file. Alternatively, you may find the the latest
|
|
php.ini from SVN helpful too.
|
|
|
|
Example 5-1. php.ini example
|
|
; any text on a line after an unquoted semicolon (;) is ignored
|
|
[php] ; section markers (text within square brackets) are also ignored
|
|
; Boolean values can be set to either:
|
|
; true, on, yes
|
|
; or false, off, no, none
|
|
register_globals = off
|
|
track_errors = yes
|
|
|
|
; you can enclose strings in double-quotes
|
|
include_path = ".:/usr/local/lib/php"
|
|
|
|
; backslashes are treated the same as any other character
|
|
include_path = ".;c:\php\lib"
|
|
|
|
Since PHP 5.1.0, it is possible to refer to existing .ini variables
|
|
from within .ini files. Example: open_basedir = ${open_basedir}
|
|
":/new/dir".

When using PHP as an Apache module, you can also change the
|
|
configuration settings using directives in Apache configuration files
|
|
(e.g. httpd.conf) and .htaccess files. You will need "AllowOverride
|
|
Options" or "AllowOverride All" privileges to do so.
|
|
|
|
With PHP 4 and PHP 5, there are several Apache directives that allow
|
|
you to change the PHP configuration from within the Apache
|
|
configuration files. For a listing of which directives are PHP_INI_ALL,
|
|
PHP_INI_PERDIR, or PHP_INI_SYSTEM, have a look at the List of php.ini
|
|
directives appendix.
|
|
|
|
Note: With PHP 3, there are Apache directives that correspond to
|
|
each configuration setting in the php3.ini name, except the name is
|
|
prefixed by "php3_".
|
|
|
|
php_value name value
|
|
Sets the value of the specified directive. Can be used only with
|
|
PHP_INI_ALL and PHP_INI_PERDIR type directives. To clear a
|
|
previously set value use none as the value.
|
|
|
|
Note: Don't use php_value to set boolean values. php_flag (see
|
|
below) should be used instead.
|
|
|
|
php_flag name on|off
|
|
Used to set a boolean configuration directive. Can be used only
|
|
with PHP_INI_ALL and PHP_INI_PERDIR type directives.
|
|
|
|
php_admin_value name value
|
|
Sets the value of the specified directive. This can not be used
|
|
in .htaccess files. Any directive type set with php_admin_value
|
|
can not be overridden by .htaccess or virtualhost directives. To
|
|
clear a previously set value use none as the value.
|
|
|
|
php_admin_flag name on|off
|
|
Used to set a boolean configuration directive. This can not be
|
|
used in .htaccess files. Any directive type set with
|
|
php_admin_flag can not be overridden by .htaccess or virtualhost
|
|
directives.
|
|
|
|
Example 5-2. Apache configuration example
|
|
<IfModule mod_php5.c>
|
|
php_value include_path ".:/usr/local/lib/php"
|
|
php_admin_flag safe_mode on
|
|
</IfModule>
|
|
|
|
Caution
|
|
|
|
PHP constants do not exist outside of PHP. For example, in httpd.conf
|
|
you can not use PHP constants such as E_ALL or E_NOTICE to set the
|
|
error_reporting directive as they will have no meaning and will
|
|
evaluate to 0. Use the associated bitmask values instead. These
|
|
constants can be used in php.ini
|
|
__________________________________________________________________
|
|
|
|
Changing PHP configuration via the Windows registry
|
|
|
|
When running PHP on Windows, the configuration values can be modified
|
|
on a per-directory basis using the Windows registry. The configuration
|
|
values are stored in the registry key HKLM\SOFTWARE\PHP\Per Directory
|
|
Values, in the sub-keys corresponding to the path names. For example,
|
|
configuration values for the directory c:\inetpub\wwwroot would be
|
|
stored in the key HKLM\SOFTWARE\PHP\Per Directory
|
|
Values\c\inetpub\wwwroot. The settings for the directory would be
|
|
active for any script running from this directory or any subdirectory
|
|
of it. The values under the key should have the name of the PHP
|
|
configuration directive and the string value. PHP constants in the
|
|
values are not parsed. However, only configuration values changeable in
|
|
PHP_INI_USER can be set this way, PHP_INI_PERDIR values can not.
|
|
__________________________________________________________________
|
|
|
|
Other interfaces to PHP
|
|
|
|
Regardless of how you run PHP, you can change certain values at runtime
|
|
of your scripts through ini_set(). See the documentation on the
|
|
ini_set() page for more information.
|
|
|
|
If you are interested in a complete list of configuration settings on
|
|
your system with their current values, you can execute the phpinfo()
|
|
function, and review the resulting page. You can also access the values
|
|
of individual configuration directives at runtime using ini_get() or
|
|
get_cfg_var().

Chapter 6. Installation FAQ
|
|
|
|
This section holds common questions about the way to install PHP. PHP
|
|
is available for almost any OS (except maybe for MacOS before OSX), and
|
|
almost any web server.
|
|
|
|
To install PHP, follow the instructions in Installing PHP.
|
|
|
|
1. Why shouldn't I use Apache2 with a threaded MPM in a production
|
|
environment?
|
|
|
|
2. Unix/Windows: Where should my php.ini file be located?
|
|
3. Unix: I installed PHP, but every time I load a document, I get the
|
|
message 'Document Contains No Data'! What's going on here?
|
|
|
|
4. Unix: I installed PHP using RPMS, but Apache isn't processing the
|
|
PHP pages! What's going on here?
|
|
|
|
5. Unix: I installed PHP 3 using RPMS, but it doesn't compile with the
|
|
database support I need! What's going on here?
|
|
|
|
6. Unix: I patched Apache with the FrontPage extensions patch, and
|
|
suddenly PHP stopped working. Is PHP incompatible with the
|
|
Apache FrontPage extensions?
|
|
|
|
7. Unix/Windows: I have installed PHP, but when I try to access a PHP
|
|
script file via my browser, I get a blank screen.
|
|
|
|
8. Unix/Windows: I have installed PHP, but when try to access a PHP
|
|
script file via my browser, I get a server 500 error.
|
|
|
|
9. Some operating systems: I have installed PHP without errors, but
|
|
when I try to start apache I get undefined symbol errors:
|
|
|
|
[mybox:user /src/php5] root# apachectl configtest
|
|
apachectl: /usr/local/apache/bin/httpd Undefined symbols:
|
|
_compress
|
|
_uncompress
|
|
|
|
10. Windows: I have installed PHP, but when I to access a PHP script
|
|
file via my browser, I get the error:
|
|
|
|
cgi error:
|
|
The specified CGI application misbehaved by not
|
|
returning a complete set of HTTP headers.
|
|
The headers it did return are:
|
|
|
|
11. Windows: I've followed all the instructions, but still can't get
|
|
PHP and IIS to work together!
|
|
|
|
12. When running PHP as CGI with IIS, PWS, OmniHTTPD or Xitami, I get
|
|
the following error: Security Alert! PHP CGI cannot be accessed
|
|
directly..
|
|
|
|
13. How do I know if my php.ini is being found and read? It seems like
|
|
it isn't as my changes aren't being implemented.
|
|
|
|
14. How do I add my PHP directory to the PATH on Windows?
|
|
15. How do I make the php.ini file available to PHP on windows?
|
|
16. Is it possible to use Apache content negotiation (MultiViews
|
|
option) with PHP?
|
|
|
|
17. Is PHP limited to process GET and POST request methods only?
|
|
|
|
1. Why shouldn't I use Apache2 with a threaded MPM in a production
|
|
environment?
|
|
|
|
PHP is glue. It is the glue used to build cool web applications by
|
|
sticking dozens of 3rd-party libraries together and making it all
|
|
appear as one coherent entity through an intuitive and easy to learn
|
|
language interface. The flexibility and power of PHP relies on the
|
|
stability and robustness of the underlying platform. It needs a working
|
|
OS, a working web server and working 3rd-party libraries to glue
|
|
together. When any of these stop working PHP needs ways to identify the
|
|
problems and fix them quickly. When you make the underlying framework
|
|
more complex by not having completely separate execution threads,
|
|
completely separate memory segments and a strong sandbox for each
|
|
request to play in, feet of clay are introduced into PHP's system.
|
|
|
|
If you feel you have to use a threaded MPM, look at a FastCGI
|
|
configuration where PHP is running in its own memory space.
|
|
|
|
And finally, this warning against using a threaded MPM is not as strong
|
|
for Windows systems because most libraries on that platform tend to be
|
|
threadsafe.
|
|
|
|
2. Unix/Windows: Where should my php.ini file be located?
|
|
|
|
By default on Unix it should be in /usr/local/lib which is
|
|
<install-path>/lib. Most people will want to change this at
|
|
compile-time with the --with-config-file-path flag. You would, for
|
|
example, set it with something like:
|
|
--with-config-file-path=/etc
|
|
|
|
And then you would copy php.ini-production from the distribution to
|
|
/etc/php.ini and edit it to make any local changes you want.
|
|
--with-config-file-scan-dir=PATH
|
|
|
|
On Windows the default path for the php.ini file is the Windows
|
|
directory. If you're using the Apache webserver, php.ini is first
|
|
searched in the Apaches install directory, e.g. c:\program files\apache
|
|
group\apache. This way you can have different php.ini files for
|
|
different versions of Apache on the same machine.
|
|
|
|
See also the chapter about the configuration file.
|
|
|
|
3. Unix: I installed PHP, but every time I load a document, I get the
|
|
message 'Document Contains No Data'! What's going on here?
|
|
|
|
This probably means that PHP is having some sort of problem and is
|
|
core-dumping. Look in your server error log to see if this is the case,
|
|
and then try to reproduce the problem with a small test case. If you
|
|
know how to use 'gdb', it is very helpful when you can provide a
|
|
backtrace with your bug report to help the developers pinpoint the
|
|
problem. If you are using PHP as an Apache module try something like:
|
|
|
|
* Stop your httpd processes
|
|
* gdb httpd
|
|
* Stop your httpd processes
|
|
* > run -X -f /path/to/httpd.conf
|
|
* Then fetch the URL causing the problem with your browser
|
|
* > run -X -f /path/to/httpd.conf
|
|
* If you are getting a core dump, gdb should inform you of this now
|
|
* type: bt
|
|
* You should include your backtrace in your bug report. This should
|
|
be submitted to http://bugs.php.net/
|
|
|
|
If your script uses the regular expression functions (ereg() and
|
|
friends), you should make sure that you compiled PHP and Apache with
|
|
the same regular expression package. This should happen automatically
|
|
with PHP and Apache 1.3.x
|
|
|
|
4. Unix: I installed PHP using RPMS, but Apache isn't processing the
|
|
PHP pages! What's going on here?
|
|
|
|
Assuming you installed both Apache and PHP from RPM packages, you need
|
|
to uncomment or add some or all of the following lines in your
|
|
httpd.conf file:
|
|
# Extra Modules
|
|
AddModule mod_php.c
|
|
AddModule mod_php3.c
|
|
AddModule mod_perl.c
|
|
|
|
# Extra Modules
|
|
LoadModule php_module modules/mod_php.so
|
|
LoadModule perl_module modules/libperl.so
|
|
|
|
And add:
|
|
AddType application/x-httpd-php3 .php3 # for PHP 3
|
|
AddType application/x-httpd-php .php # for PHP 4
|
|
|
|
... to the global properties, or to the properties of the VirtualDomain
|
|
you want to have PHP support added to.
|
|
|
|
5. Unix: I installed PHP 3 using RPMS, but it doesn't compile with the
|
|
database support I need! What's going on here?
|
|
|
|
Due to the way PHP 3 built, it is not easy to build a complete flexible
|
|
PHP RPM. This issue is addressed in PHP 4. For PHP 3, we currently
|
|
suggest you use the mechanism described in the INSTALL.REDHAT file in
|
|
the PHP distribution. If you insist on using an RPM version of PHP 3,
|
|
read on...
|
|
|
|
The RPM packagers are setting up the RPMS to install without database
|
|
support to simplify installations and because RPMS use /usr/ instead of
|
|
the standard /usr/local/ directory for files. You need to tell the RPM
|
|
spec file which databases to support and the location of the top-level
|
|
of your database server.
|
|
|
|
This example will explain the process of adding support for the popular
|
|
MySQL database server, using the mod installation for Apache.
|
|
|
|
Of course all of this information can be adjusted for any database
|
|
server that PHP supports. We will assume you installed MySQL and Apache
|
|
completely with RPMS for this example as well.
|
|
|
|
* First remove mod_php3 :
|
|
|
|
rpm -e mod_php3
|
|
|
|
* Then get the source rpm and INSTALL it, NOT --rebuild
|
|
|
|
rpm -Uvh mod_php3-3.0.5-2.src.rpm
|
|
|
|
* Then edit the /usr/src/redhat/SPECS/mod_php3.spec file
|
|
In the %build section add the database support you want, and the
|
|
path.
|
|
For MySQL you would add --with-mysql=/usr The %build section will
|
|
look something like this:
|
|
|
|
./configure --prefix=/usr \
|
|
--with-apxs=/usr/sbin/apxs \
|
|
--with-config-file-path=/usr/lib \
|
|
--enable-debug=no \
|
|
--enable-safe-mode \
|
|
--with-exec-dir=/usr/bin \
|
|
--with-mysql=/usr \
|
|
--with-system-regex
|
|
|
|
* Once this modification is made then build the binary rpm as
|
|
follows:
|
|
|
|
rpm -bb /usr/src/redhat/SPECS/mod_php3.spec
|
|
|
|
* Then install the rpm
|
|
|
|
rpm -ivh /usr/src/redhat/RPMS/i386/mod_php3-3.0.5-2.i386.rpm
|
|
|
|
Make sure you restart Apache, and you now have PHP 3 with MySQL support
|
|
using RPM's. Note that it is probably much easier to just build from
|
|
the distribution tarball of PHP 3 and follow the instructions in
|
|
INSTALL.REDHAT found in that distribution.
|
|
|
|
6. Unix: I patched Apache with the FrontPage extensions patch, and
|
|
suddenly PHP stopped working. Is PHP incompatible with the Apache
|
|
FrontPage extensions?
|
|
|
|
No, PHP works fine with the FrontPage extensions. The problem is that
|
|
the FrontPage patch modifies several Apache structures, that PHP relies
|
|
on. Recompiling PHP (using 'make clean ; make') after the FP patch is
|
|
applied would solve the problem.
|
|
|
|
7. Unix/Windows: I have installed PHP, but when I try to access a PHP
|
|
script file via my browser, I get a blank screen.
|
|
|
|
Do a 'view source' in the web browser and you will probably find that
|
|
you can see the source code of your PHP script. This means that the web
|
|
server did not send the script to PHP for interpretation. Something is
|
|
wrong with the server configuration - double check the server
|
|
configuration against the PHP installation instructions.
|
|
|
|
8. Unix/Windows: I have installed PHP, but when try to access a PHP
|
|
script file via my browser, I get a server 500 error.
|
|
|
|
Something went wrong when the server tried to run PHP. To get to see a
|
|
sensible error message, from the command line, change to the directory
|
|
containing the PHP executable (php.exe on Windows) and run php -i. If
|
|
PHP has any problems running, then a suitable error message will be
|
|
displayed which will give you a clue as to what needs to be done next.
|
|
If you get a screen full of HTML codes (the output of the phpinfo()
|
|
function) then PHP is working, and your problem may be related to your
|
|
server configuration which you should double check.
|
|
|
|
9. Some operating systems: I have installed PHP without errors, but
|
|
when I try to start apache I get undefined symbol errors:
|
|
[mybox:user /src/php5] root# apachectl configtest
|
|
apachectl: /usr/local/apache/bin/httpd Undefined symbols:
|
|
_compress
|
|
_uncompress
|
|
|
|
This has actually nothing to do with PHP, but with the MySQL client
|
|
libraries. Some need --with-zlib, others do not. This is also covered
|
|
in the MySQL FAQ.
|
|
|
|
10. Windows: I have installed PHP, but when I to access a PHP script
|
|
file via my browser, I get the error:
|
|
cgi error:
|
|
The specified CGI application misbehaved by not
|
|
returning a complete set of HTTP headers.
|
|
The headers it did return are:
|
|
|
|
This error message means that PHP failed to output anything at all. To
|
|
get to see a sensible error message, from the command line, change to
|
|
the directory containing the PHP executable (php.exe on Windows) and
|
|
run php -i. If PHP has any problems running, then a suitable error
|
|
message will be displayed which will give you a clue as to what needs
|
|
to be done next. If you get a screen full of HTML codes (the output of
|
|
the phpinfo() function) then PHP is working.
|
|
|
|
Once PHP is working at the command line, try accessing the script via
|
|
the browser again. If it still fails then it could be one of the
|
|
following:
|
|
|
|
* File permissions on your PHP script, php.exe, php5ts.dll, php.ini
|
|
or any PHP extensions you are trying to load are such that the
|
|
anonymous internet user ISUR_<machinename> cannot access them.
|
|
* The script file does not exist (or possibly isn't where you think
|
|
it is relative to your web root directory). Note that for IIS you
|
|
can trap this error by ticking the 'check file exists' box when
|
|
setting up the script mappings in the Internet Services Manager. If
|
|
a script file does not exist then the server will return a 404
|
|
error instead. There is also the additional benefit that IIS will
|
|
do any authentication required for you based on the NTLanMan
|
|
permissions on your script file.
|
|
|
|
11. Windows: I've followed all the instructions, but still can't get
|
|
PHP and IIS to work together!
|
|
|
|
Make sure any user who needs to run a PHP script has the rights to run
|
|
php.exe! IIS uses an anonymous user which is added at the time IIS is
|
|
installed. This user needs rights to php.exe. Also, any authenticated
|
|
user will also need rights to execute php.exe. And for IIS4 you need to
|
|
tell it that PHP is a script engine. Also, you will want to read this
|
|
faq.
|
|
|
|
12. When running PHP as CGI with IIS, PWS, OmniHTTPD or Xitami, I get
|
|
the following error: Security Alert! PHP CGI cannot be accessed
|
|
directly..
|
|
|
|
You must set the cgi.force_redirect directive to 0. It defaults to 1 so
|
|
be sure the directive isn't commented out (with a ;). Like all
|
|
directives, this is set in php.ini
|
|
|
|
Because the default is 1, it's critical that you're 100% sure that the
|
|
correct php.ini file is being read. Read this faq for details.
|
|
|
|
13. How do I know if my php.ini is being found and read? It seems like
|
|
it isn't as my changes aren't being implemented.
|
|
|
|
To be sure your php.ini is being read by PHP, make a call to phpinfo()
|
|
and near the top will be a listing called Configuration File (php.ini).
|
|
This will tell you where PHP is looking for php.ini and whether or not
|
|
it's being read. If just a directory PATH exists than it's not being
|
|
read and you should put your php.ini in that directory. If php.ini is
|
|
included within the PATH than it is being read.
|
|
|
|
If php.ini is being read and you're running PHP as a module, then be
|
|
sure to restart your web server after making changes to php.ini
|
|
|
|
14. How do I add my PHP directory to the PATH on Windows?
|
|
|
|
On Windows NT, 2000, XP and 2003:
|
|
|
|
* Go to Control Panel and open the System icon (Start -> Settings ->
|
|
Control Panel -> System, or just Start -> Control Panel -> System
|
|
for Windows XP/2003)
|
|
* Go to the Advanced tab
|
|
* Click on the 'Environment Variables' button
|
|
* Look into the 'System Variables' pane
|
|
* Find the Path entry (you may need to scroll to find it)
|
|
* Double click on the Path entry
|
|
* Enter your PHP directory at the end, including ';' before (e.g.
|
|
;C:\php)
|
|
* Press OK and restart your computer
|
|
|
|
On Windows 98/Me you need to edit the autoexec.bat file:
|
|
|
|
* Open the Notepad (Start -> Run and enter notepad)
|
|
* Open the C:\autoexec.bat file
|
|
* Locate the line with PATH=C:\WINDOWS;C:\WINDOWS\COMMAND;..... and
|
|
add: ;C:\php to the end of the line
|
|
* Save the file and restart your computer
|
|
|
|
Note: Be sure to reboot after following the steps above to ensure
|
|
that the PATH changes are applied.
|
|
|
|
The PHP manual used to promote the copying of files into the Windows
|
|
system directory, this is because this directory (C:\Windows, C:\WINNT,
|
|
etc.) is by default in the systems PATH. Copying files into the Windows
|
|
system directory has long since been deprecated and may cause problems.
|
|
|
|
15. How do I make the php.ini file available to PHP on windows?
|
|
|
|
There are several ways of doing this. If you are using Apache, read
|
|
their installation specific instructions (Apache 1, Apache 2),
|
|
otherwise you must set the PHPRC environment variable:
|
|
|
|
On Windows NT, 2000, XP and 2003:
|
|
|
|
* Go to Control Panel and open the System icon (Start -> Settings ->
|
|
Control Panel -> System, or just Start -> Control Panel -> System
|
|
for Windows XP/2003)
|
|
* Go to the Advanced tab
|
|
* Click on the 'Environment Variables' button
|
|
* Look into the 'System variables' pane
|
|
* Click on 'New' and enter 'PHPRC' as the variable name and the
|
|
directory where php.ini is located as the variable value (e.g.
|
|
C:\php)
|
|
* Press OK and restart your computer
|
|
|
|
On Windows 98/Me you need to edit the autoexec.bat file:
|
|
|
|
* Open the Notepad (Start -> Run and enter notepad)
|
|
* Open the C:\autoexec.bat file
|
|
* Add a new line to the end of the file: set PHPRC=C:\php (replace
|
|
C:\php with the directory where php.ini is located). Please note
|
|
that the path cannot contain spaces. For instance, if you have
|
|
installed PHP in C:\Program Files\PHP, you would enter
|
|
C:\PROGRA~1\PHP instead.
|
|
* Save the file and restart your computer
|
|
|
|
16. Is it possible to use Apache content negotiation (MultiViews
|
|
option) with PHP?
|
|
|
|
If links to PHP files include extension, everything works perfect. This
|
|
FAQ is only for the case when links to PHP files don't include
|
|
extension and you want to use content negotiation to choose PHP files
|
|
from URL with no extension. In this case, replace the line AddType
|
|
application/x-httpd-php .php with:
|
|
# PHP 4
|
|
AddHandler php-script php
|
|
AddType text/html php
|
|
|
|
# PHP 5
|
|
AddHandler php5-script php
|
|
AddType text/html php
|
|
|
|
This solution doesn't work for Apache 1 as PHP module doesn't catch
|
|
php-script.

|

|
17. Is PHP limited to process GET and POST request methods only?
|
|
|
|
No, it is possible to handle any request method, e.g. CONNECT. Proper
|
|
response status can be sent with header(). If only GET and POST methods
|
|
should be handled, it can be achieved with this Apache configuration:
|
|
<LimitExcept GET POST>
|
|
Deny from all
|
|
</LimitExcept>
