run code in 300+ PHP versions simultaneously
<?php $urlGray = array(); for ($i=1; $i<=6; $i++) { $urlGray[$i] = "foo"; } echo($urlGray[2]); ?>

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).
