#40587 [NEW]: Attempt to call undefined function gives a fatal error instead of recoverable

[mathiasrav at gmail dot com]

From: mathiasrav at gmail dot com
Operating system: WinXP
PHP version: 5.2.1
PHP Bug Type: Feature/Change Request
Bug description: Attempt to call undefined function gives a fatal error instead of recoverable

Description:
------------
If you try to call an undefined function, PHP raises an E_ERROR and
crashes - not a catchable E_RECOVERABLE_ERROR.
This isn't a problem for web-related scripts, but for
maintainence/shell-like scripts, this can be a help. I have a script with
an idle-loop that calls (includes) module-files, and if a change to one of
these has a typo, all socket connections and the like are killed.

Reproduce code:
---------------
<?php
function returntrue(){return true;}
seterrorhandler('returntrue', E_RECOVERABLE_ERROR);
qweasd();
echo 'Carrying on...';
?>

Expected result:
----------------
The call to qweasd() should return false or null. If the programmer has
made the script able to recover from calls to unknown functions, he must
have written code that can tell the difference between the return code
from a known and an unknown function.

Actual result:
--------------
The script halts.

A little change to the description-section - PHP doesn't crash, it
simply halts script execution. The *script* "crashes".
