run code in 300+ PHP versions simultaneously
<?php $a = 1; $c = 0; $d = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]; $b = 2; add($a, $b); function add($a, $b) { return $a + $b; }

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).
