Bug description: Create a way to capture/unset headers sent by ob_gzhandler ?
Description:
------------
Hi,
I would like to implement a fine tuned output compression mechanism, and I
can't with any of the actual PHP function.
Basically, what I want is a function that does exactly what ob_gzhandler
does, but without sending the headers is sends.
I've thought about two possibilities to enable this :
- the first is to implement a generic way to manage the headers buffer, ie
a way to delete a header, not just replace it. This is a very generic
solution, and I think it would benefit to PHP in general.
- the second would be to add an option, maybe a third parameter, to
ob_gzhandler.
What do you think of that ?
At least, it would be worth for me. Maybe for others too ?
Reproduce code:
---------------
Here is an example of a simple thing that don't work, but could be
interesting :
<?php
function my_obgz($buffer, $mode)
{
// This example miss some headers management,
// but the basic idea is here.
// And in fact, this headers managmement is impossible
// with actual the PHP functions.
$gz = ob_gzhandler($buffer, $mode);
if ($mode == (PHP_OUTPUT_HANDLER_START | PHP_OUTPUT_HANDLER_END))
{
if (strlen($gz) < strlen($buffer)) $buffer =& $gz;
}
else $buffer =& $gz;
return $buffer;
}
ob_start('my_obgz');
