run code in 300+ PHP versions simultaneously
<?php $string='Foo, Bar, Test, X, Y, Z,'; $pos=0; $count=0; while(($pos = strpos($string, ',',$pos)) !== FALSE){ $count++; $pos++; // This ends }

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).
