run code in 300+ PHP versions simultaneously
<?php $a = 0; $b = 0; for($i = 1; $i <= 10; $i++) { $a += pow($i, 2); $b += $i; } $c = pow($b, 2) - $a; echo "A: {$a}\nB: {$b}\nC: {$c}";

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).
