run code in 300+ PHP versions simultaneously
<?php $d = @preg_match("ascea(", "test"); // invalid regex if($d === FALSE) { print "Error in regex."; // get detailed info if needed with preg_last_error }

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).
