to be called as all the headers are being sent and after all
of the default headers have been merged.
headers_list(), header_remove() and header() can all be used
inside the callback.
<?php
header('Content-Type: text/plain');
header('X-Test: foo');
function foo() {
foreach (headers_list() as $header) {
if (strpos($header, 'X-Powered') !== false) {
header_remove('X-Powered-By');
}
header_remove('X-Test');
}
}
$result = header_register_callback('foo');
echo "a";
disabled when the header "Content-length" is set.
#One could argue that any output handler could change the size of the
#response, so this exception for zlib.output_compression is an
#inconsistency. However, zlib.output_compression is presented as a
#performance setting, whose value should have no effect on the
#correctness of the scripts. This was not the case. Setting the
#header "content-length" and enabling zlib.output_compression was
#a recipe for infringing section 4.4 of RFC 2616.
requests--let's see what I can dig out of the bugtracker for NEWS--
and while crossing the road:
* implemented new zlib API
* fixed up ext/tidy (what was "s&" in zend_parse_parameters() supposed to do?)
Thanks to Jani and Felipe for pioneering.
* Removed ini options, safe_mode*
* Removed --enable-safe-mode --with-exec-dir configure options on Unix
* Updated extensions, SAPI's and core
* php_get_current_user() is now declared in main.c, thrus no need to include safe_mode.h anymore
I am sorry I tried fixing PHP without extensive discussion on the mailing list.

Hope all the relevant parties are satisfied.
[DOC] proto void header_remove([string header_name])
Removes an HTTP header previously set using header()
The header_name parameter is optionnal, all headers are
removed if it is not set
[SAPIs] The header_handler callback in sapi_module_struct has
been changed, it now take a new argument.
When it is set to SAPI_HEADER_DELETE, sapi_header->header is
the name of an header, header_handler has to delete it.
When it is set to SAPI_HEADER_DELETE_ALL, header_handler has
to delete all headers.
When sapi_header_op_enum is SAPI_HEADER_ADD or _REPLACE,
sapi_header->header is in the form "Name: value", header_handler
has to add or replace the given header.
In all cases, header_handler must not free sapi_header or
sapi_header->header. SAPI_HEADER_ADD must be returned if the
header has been added or replaced, or 0 in other cases.
After the sigsetjmp change, this is patch #2 in an effort to get some
sanity restored to signal handling in PHP.
This patch does two things. First, it makes it possible to reset the
timeout without resetting the signal handlers. This is important for
cases where an extension may have deferred signals in its MINIT in order
to implement critical sections. It also lays the groundwork for cleaning
up our signal handling and perhaps eventually implementing our own
signal deferring mechanism so we can have true critical sections.
The second thing this does is to make it possible to terminate the current
child process (only for Apache1 at the moment) on a timeout. There are
a number of extensions that are unhappy about being longjmp'ed out of
and when this happens on a timeout they are left in an inconsistent state.
By turning on exit_on_timeout you can now force the process to terminate
on a timeout which will clean up any hanging locks and/or memory left
hanging after the longjmp.
