run code in 200+ php & hhvm versions
Bugs & Features
<?php $ts1 = '5-20-2013'; $ts2 = '20-5-2013'; var_dump(date('r', strtotime($ts1))); var_dump(date('r', strtotime($ts2)));

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.
