<?php $date = "4/23/15"; echo $x = '~^(' . implode('|', range(1, 12)) . ')\/(' . implode('|', range(1, 31)) . ')\/[0-9]{2}$~'; preg_match($x, $date, $m); var_dump($m);

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).
