<?php $datetime1 = new DateTime(); $datetime2 = new DateTime('2015-12-24'); $interval = $datetime1->diff($datetime2); $elapsed = $interval->format('%d'); echo $elapsed;

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).
