run code in 300+ PHP versions simultaneously
<?php $range = "2008-2013"; $year = "2008"; $shite = "-2013"; $regex = "/(\d{4}-\d{4}?|\d{4})/is"; $matches = array(); preg_match($regex, $range, $matches); preg_match($regex, $year, $matches); preg_match($regex, $shite, $matches); print_r($matches); ?>

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).
