run code in 300+ PHP versions simultaneously
<?php function x($n) { $z="printf"; for($i = 1; $i <= $n; $i++) { $n % $i == 0 && $i != $n ? $f[]=$i & z("$i "): 0; } array_sum($f) == $n ? z('P') : z('I'); } x(28);

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).
