run code in 300+ PHP versions simultaneously
<?php $time1 = '2014-08-26 14:35:29'; $time2 = '2014-08-26 15:35:29'; $strtotime1 = strtotime($time1); $strtotime2 = strtotime($time2); $hourdiff = (strtotime($strtotime2) - strtotime($strtotime1))/3600, 1; echo $hourdiff; exit; echo $strtotime1; echo "\n"; echo $strtotime2; echo "\n"; echo $strtotime2 - $strtotime1;

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).
