Hi,

I have found the following bug with the function call_user_func():

If the user function you are trying to call with 'call_user_func' requires any of its parameters to be passed by reference, PHP issues a warning stating that the function doesn't exist.

Example:

<?php
function testme(&$param) {
 var_dump($param);
}

$func = "testme";
$param = array(1, 2);

call_user_func($func, $param);

?>

Result:

<br>
<b>Warning</b>:  Unable to call testme() - function does not exist in <b>t.php</b> on line <b>1</b><br>
