<?php $dateStart = '2016/12/31'; list($yS, $mS, $dS) = preg_split('/[/\.-]/', $dateStart); echo $dS;

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).
Note: hhvm uses a JIT which only kicks in after a few runs. Since we run scripts only once, hhvm always runs slower.
