run code in 300+ PHP versions simultaneously
<?php $d1 = strtotime("2015-03-31"); $d2 = strtotime("2016-03-01"); echo abs((date('Y', $d2) - date('Y', $d1))*12 + (date('m', $d2) - date('m', $d1))); ?>

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).
