Well, I thought that the function call_user_func_array() is supposed to be
called this way. What good is it anyway? I suggest 'call_user_func_array'
should
be removed as it is not needed and also doesn't work with user functions
that
expect arguments by reference.

This script fails:

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

$name = "get_reference_as_arg";
$param1 = array(1, 2);

call_user_func_array($name, array($param1));
?>
