run code in 200+ php & hhvm versions
Bugs & Features
<?php $startTime = strtotime('2013-01-01 3:00'); $finishTime = strtotime('2013-03-01 3:00'); $lastMonthDay = strtotime(sprintf('last day of Jan'), $startTime); $dateTime = strtotime(sprintf('%s %s %s', 'Mon', '3:00', 'Jan'), $startTime); for (;$dateTime <= $lastMonthDay; $dateTime = strtotime('+1 week', $dateTime)) { echo date ('d-m-Y H:i', $dateTime) . PHP_EOL; }

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.
