run code in 300+ PHP versions simultaneously
<?php $sampleString = "082307"; $length = strlen($sampleString); for(x=0; x<$length; x++) echo chunk_split($sampleString, 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).
