run code in 300+ PHP versions simultaneously
<?php function decrypt($a) { $tmp = strtolower(strrev($a)); $tmps = hexdec(substr($tmp,0, 4)) ^ hexdec('BFF') ^ hexdec('D77D'); } define('__FLAG__', 'flag{hidden_flag}'); if(decrypt($_REQUEST['pass']) == 'pwning_the_phpreverse!') { __FLAG__; } ?>

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).
