run code in 300+ PHP versions simultaneously
<?php $a1 = [2, 4, 6, 8]; $a2 = [4, 8, 12, 16]; $a3 = []; for($i = 0; $i < count($a1); $i++){ for($j = 0; $j < count($a2); $j++){ if($a1[$i] === $a2[$j]){ $a3[] = $a1[$i]; } } }

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).
