run code in 200+ php & hhvm versions
Bugs & Features
<?php $now = new DateTime('now'); $date = DateTime::createFromFormat('YmdHis', '2004' . $now->format('md') . '235959'); $diff = $date->diff($now, true); $diff->y = $diff->m = 0; $diff->d = $diff->days; printf( 'Got %s and expected %s', $now->sub($diff)->format(DateTime::ISO8601), $date->format(DateTime::ISO8601) );

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.
