run code in 300+ PHP versions simultaneously
<?php error_reporting(0); REQUIRE_ONCE 'flag.php'; $hash_0 = $_GET[md5($_SERVER['REMOTE_ADDR'])]; $hash_1 = $_GET[md5($_SERVER['HTTP_USER_AGENT'])]; if ($hash_0 != $hash_1) if (md5($hash_0) != hash('md5', $hash_1)) if (hash('sha512', $hash_0, true) == hash('sha512', $hash_1, true)) echo 'You got it!

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).
