run code in 200+ php & hhvm versions
Bugs & Features
<?php $year = 2013; $week = 25; $Jan1 = mktime(0, 0, 0, 1, 1, $year); $MondayOffset = (11 - date('w', $Jan1)) % 7 - 3; $desiredMonday = strtotime(($week - 1) . ' weeks ' . $MondayOffset . ' days', $Jan1); $desiredSunday = strtotime('+0 week 0 days 1 hour', $desiredMonday); var_dump( $desiredMonday, $desiredSunday );

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.
