run code in 300+ PHP versions simultaneously
<?php $string = "*@combinationRule don't remove the reference"; echo strpos($string, "combinationRule"), "\n"; echo substr($string, strlen($string));

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).
