Bug description: call_user_func_array returns NULL (instead of FALSE) for
invalid callbacks
Description:
------------
call_user_func_array() claims it "Returns the function result, or FALSE on
error."
My testing shows it returns NULL if the callback function is not a valid
callback.
Reproduce code:
---------------
<?php
function callable()
{ return 'Good.'; }
$return = call_user_func_array('callable',array());
var_dump($return);
$return = call_user_func_array('not_callable',array());
var_dump($return);
?>
Expected result:
----------------
string(5) "Good."
Warning: call_user_func_array() [function.call-user-func-array]: First
argument is expected to be a valid callback, 'not_callable' was given in
_______ on line 9
FALSE
Actual result:
--------------
string(5) "Good."
Warning: call_user_func_array() [function.call-user-func-array]: First
argument is expected to be a valid callback, 'not_callable' was given in
_______ on line 9
NULL
