run code in 300+ PHP versions simultaneously
<?php $time = microtime(true); for ($i = 0; $i < 10000; $i++) { preg_match('/^label-(.+)/', $key, $matches); } $time = microtime(true) - $time; echo 'preg_match() took ' . number_format($time, 3) . ' seconds' . "\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).
