The $result parameter, for some reason, is being received by reference. But it doesn't make any sense, does it? This variable is destroyed right after zend_call_function call was made. I know, it might seem like pretty minor bug, but it confused me (and my colleagues) so many times. It may seem like one supposed to result in this variable instead of returning it, so there lays a confusion... ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65894&edit=1
