run code in 300+ PHP versions simultaneously
<?php $n=3618;$rev=0; while($n!=0) { $rem=$n%2; $rev=$rev*10+$rem; $n=$n/1; } echo 'reverse of no is:'$rev; ?>

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).
