<?php preg_match_all("/(user1)(user2)(user3)(user4)(user5)/", "user1 user2 user3 user4 <> user5", $matches); echo "<pre>"; print_r($matches); echo "</pre>";

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).
