Bug description:E_RECOVERABLE_ERROR when output buffering in output buffering
handler
Description:
------------
Output buffering inside output buffering handler is currently forbidden.
Ideally, this limitation could be removed, but as this may be too much
work, I mostly really miss some way to test whether my code is running
inside an output buffering handler or not (for example in a custom error
handler).
PHP really miss a way to check for this situation.
Currently, when using output buffering in an output buffering handler
context, an E_ERROR is thrown. Could it be possible to trigger an
E_RECOVERABLE_ERROR instead? This would allow me to catch the situation and
degrade gracefully.
Or maybe a new special function "ob_in_handler()", returning a boolean, is
a better idea ?
Test script:
---------------
<?php
ob_start('abc');
function abc()
{
ob_start();
}
?>
Expected result:
----------------
PHP Catchable fatal error: ob_start(): Cannot use output buffering in
output buffering display handlers in [...] on line 5
Actual result:
--------------
PHP Fatal error: ob_start(): Cannot use output buffering in output
buffering display handlers in [...] on line 5
