run code in 300+ PHP versions simultaneously
<?php $un = "jarrod"; $uid = "1"; $key = uniqid($uid."_"); $ip = "124.168.106.184"; $time = time(); $hash = md5("$uid$ip$time"); print "$key\n"; print "$hash";

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).
