<?php

try {
    session_set_save_handler(
        array(&$arf, 'open'),

--EXPECTF--
Deprecated: session_set_save_handler(): Providing individual callbacks instead of an object implementing SessionHandlerInterface is deprecated in %s on line %d
session_set_save_handler(): Argument #1 ($open) must be a valid callback, first array member is not a valid class name or object
Done
