run code in 200+ php & hhvm versions
Bugs & Features
<?php $date = new DateTime('now'); $firstOfMonth = $date->modify('start of month')->format(DATE_ISO8601); $lastOfMonth = $date->modify('last day of month')->format(DATE_ISO8601); var_dump(array($firstOfMonth, $lastOfMonth));

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).
Note: hhvm uses a JIT which only kicks in after a few runs. Since we run scripts only once, hhvm always runs slower.
