run code in 300+ PHP versions simultaneously
<?php if(preg_match('/[^a-z_\-0-9]/i', 'dani_>_938')) { echo "not valid string"; } else { echo "valid 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).
