run code in 300+ PHP versions simultaneously
<?php $a = 'string'; $b = 'string'; $tmp = array_unique(array($a, $b)); if (-count($tmp)+2) echo 'They match!';

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).
