run code in 300+ PHP versions simultaneously
<?php $b= 1; $k =0 ; for($i=1; $i<=5; $i++) { echo "Data ".$i." To user ".$b."<br>\n"; if($b == 2 && $k == 1) { $b--; } else { if($b == 2) $k++; $b++; } }

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).
