<?php $datetime1 = new DateTime('2009-10-17'); $datetime2 = new DateTime('2009-10-13'); $interval = $datetime1->diff($datetime2); var_dump($interval); echo $interval->format('%R%a days');

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).
