run code in 300+ PHP versions simultaneously
<?php function f1($x) { $sum=2; for($i=$x;$i>0;$i--){ $sum+=$i; } return $sum;} $a=f1(6); echo $a; ?>

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).
