Description:
------------
call_user_func()/array_walk() doesn't accept 
array($obj, "func") callback anymore...

(See Zend/tests/bug31720.phpt && Zend/tests/bug19859.phpt)

Reproduce code:
---------------
<?php
$array = array('at least one element');

array_walk($array, array($nonesuchvar,'show'));
?>


Expected result:
----------------
Notice: Undefined variable: nonesuchvar in %s on line %d

Notice: Non-callable array passed to zend_call_function() 
in %s on line %d

Warning: array_walk(): Unable to call Array() - function 
does not exist in %s on line %d


Actual result:
--------------
Notice: Undefined variable: nonesuchvar 
in /usr/src/php/6.0/Zend/tests/bug31720.php on line 4

Warning: array_walk() expects parameter 2 to be valid 
callback, array given 
in /usr/src/php/6.0/Zend/tests/bug31720.php on line 4

The Zend/tests/bug19859.phpt is still broken, others seem to be fixed.
Marcus, your fcall_info stuff breaks it, please look into it.
I tried to fix it, but got lost in the code you wrote.
zend_call_function() should detect if __call() is used and pass the real function name as the first param.

Can someone enlighten me how the reproduce code is supposed to do anything? You can't call methods on non-existing objects...

This bug has been fixed in CVS.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at
http://snaps.php.net/.
 
Thank you for the report, and for helping us make PHP better.

Fixed already in April by me
