run code in 300+ PHP versions simultaneously
<?php preg_match('@^(?:http://)?([^/]+)@i', "http://www.php.net/index.html", $matches); $host = $matches[1]; // get last two segments of host name preg_match('/[^.]+\.[^.]+$/', $host, $matches); echo "domain name is: {$matches[0]}\n";

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).
