run code in 300+ PHP versions simultaneously
<?php $i = 1; for($f = 0; $f <= 20; $f++) { echo "F".$f." = ".intval((($f-1)+$f-2))."\n"; $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).
