<?php class A implements Serializable { public function serialize() { return 'foo'; } public function unserialize($data) { } } class B extends A { public function serialize() { return 'bar'; } } var_dump(serialize(new A()));

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
