run code in 300+ PHP versions simultaneously
<?php echo preg_match('@^(?!<)\w(?<!(,|.))@','test,'); echo preg_match('@^(?!<)\w(?<!(,|.))@','test');

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).
