PHP 5.2 UPDATE INFO
===============================
Changes in PHP datetime support
===============================
Since PHP 5.1, there has been an extension named 'date' in the PHP core. This
is the new implementation of PHP's datetime support. Although it will attempt
to guess your system's timezone setting, you should set the timezone manually.
You can do this in any of three ways:
1) in your php.ini using the date.timezone INI directive
2) on your system using the TZ environmental variable
3) from your script using the convenience function date_default_timezone_set()
All supported timezones are listed in the PHP Manual at
http://www.php.net/manual/timezones.php.
With the advent of PHP 5.2, there are object representations of the date and
timezone, named DateTime and DateTimeZone respectively. You can see the methods
and constants available to the new classes by running
php --rc DateTime
php --rc DateTimeZone
under PHP CLI - or see the PHP Manual under Date/Time functions, or the 'NEW
FEATURES' section below. All methods map to existing procedural date functions.
==================================
Items from the NEWS file explained
==================================
- Added new error mode E_RECOVERABLE_ERROR. (Derick, Marcus, Tony)
Some of the existing E_ERROR conditions have been converted to something that
you can catch with a user-defined error handler. If an E_RECOVERABLE_ERROR is
not handled, it will behave in the same way as E_ERROR behaves in all versions
of PHP. Errors of this type are logged as 'Catchable fatal error'.
- Changed E_ALL error reporting mode to include E_RECOVERABLE_ERROR. (Marcus)
This change means that the value of the E_ALL error_reporting constant is now
6143, where the previous value was 2047. If you are setting the error_reporting
mode from either the Apache config file or the .htaccess files, you will need
to adjust the value accordingly. The same applies if you use the numeric value
rather than the constant in your PHP scripts.
- Added support for constructors in interfaces to force constructor signature
checks in implementations. (Marcus)
Starting with PHP 5.2, interfaces can have constructors. However, if you choose
to declare a constructor in an interface, each class implementing that interface
MUST include a constructor with a signature matching that of the base interface
constructor. By 'signature' we mean the parameter and return type definitions,
including any type hints and including whether the data is passed by reference
or by value.
- Changed __toString to be called wherever applicable. (Marcus)
The magic method __toString() will now be called in a string context, that
is, anywhere an object is used as a string. When implementing your __toString()
method in a class, you should be aware that the script will terminate if
your function throws an exception.
The PHP 5.0/5.1 fallback - returning a string that contains the object
identifier - has been dropped in PHP 5.2. It became problematic because
an object identifier cannot be considered unique. This change will mean
that your application is flawed if you have relied on the object identifier
as a return value. An attempt to use that value as a string will now result
in a catchable fatal error (see above).
Even with __toString(), objects cannot be used as array indices or keys. We
may add built-in hash support for this at a later date, but for PHP 5.2 you
will need to either provide your own hashing or use the new SPL function
spl_object_hash().
- Added RFC2397 (data: stream) support. (Marcus)
The introduction of the 'data' URL scheme has the potential to lead to a
change of behaviour under Windows. If you are working with an NTFS
file system and making use of meta streams in your application, and if you
just happen to be using a file with the name 'data:' that is accessed without
any path information - it won't work any more. The fix is to use the 'file:'
protocol when accessing it.
There is information about the RFC at http://www.faqs.org/rfcs/rfc2397.html.
- Added allow_url_include ini directive to complement allow_url_fopen. (Rasmus)
This useful option makes it possible to differentiate between standard
file operations on remote files, and the inclusion of remote files. While the
former is usually desirable, the latter can be a security risk if used naively.
Starting with PHP 5.2, you can allow remote file operations while
disallowing the inclusion of remote files in local scripts. In fact, this
is the default configuration.
- Dropped abstract static class functions. (Marcus)
Due to an oversight, PHP 5.0 and 5.1 allowed abstract static functions in
classes. In PHP 5.2, only interfaces can have them.
- Removed extensions (Derick, Tony)
The filepro and hwapi extensions have been moved to PECL and are no longer
part of the PHP distribution. The PECL package version of these extensions
will be created according to user demand.
- Added extensions (Rasmus, Derick, Pierre)
The JSON extension implements the JavaScript Object Notation (JSON)
data interchange format. This extension is enabled by default.
The Filter extension validates and filters data, and is designed for
use with insecure data such as user input. This extension is enabled
by default; the default mode RAW does not impact input data in any way.
The Zip extension enables you to transparently read or write ZIP
compressed archives and the files inside them.
Please refer to the NEW FEATURES section below or to the PHP Manual
for details.
- Improved memory manager and increased default memory limit (Dmitry)
The new memory manager allocates less memory and works faster than the
previous incarnation. It allocates memory from the system in large blocks,
and then manages the heap by itself. The memory_limit value in php.ini is
checked, not for each emalloc() call (as before), but for actual blocks
requested from the system. This means that memory_limit is far more
accurate than it used to be, since the old memory manager didn't calculate
all the memory overhead used by the malloc library.
Thanks to this new-found accuracy memory usage may appear to have increased,
although actually it has not. To accommodate this apparent increase, the
default memory_limit setting was also increased - from 8 to 16 megabytes.
- Changed priority of PHPRC environment variable on win32 (Dmitry)
The PHPRC environment variable now takes priority over the path stored
in the Windows registry.
- CLI SAPI no longer checks cwd for php.ini or the php-cli.ini file (Edin)
In PHP 5.1 an undocumented feature was added that made the CLI binary check
the current working directory for a PHP configuration file, potentially
leading to unpredictable behavior if an unexpected configuration file were
read. This functionality was removed in 5.2, and PHP will no longer search
CWD for the presence of php.ini or php-cli.ini files.
- Added a notice when performing modulus 0 operation (Tony)
In earlier versions of PHP, performing integer % 0 did not emit any
warning messages, instead returning an unexpected return value of FALSE.
As of PHP 5.2 this operation will emit an E_WARNING, as is the case in all
other instances where division by zero is performed.
- As a side-effect of a change made to prevent duplicate error messages
when error_tracking is On [Ilia], it is now necessary to return FALSE
from your error handler in order to populate $php_errormsg. This allows
you to fine-grain the levels of the messages stored.
