run code in 300+ PHP versions simultaneously
<?php $a = 'a'; $b = '3'; echo (isset ($a) && isset ($b) && !is_numeric (($a * $b) . '') ) ? 1 : 0; ?>

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).
