run code in 300+ PHP versions simultaneously
<?php $php = '<?php $var = readonly /* commment */ ();'; foreach (token_get_all($php) as $token) { if (is_array($token)) { echo token_name($token[0]) . "\n"; } else { echo $token . "\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).
