run code in 200+ php & hhvm versions
<?php $arr = array("D"=>"dog","a"=>"cat","A"=>"moose","d"=>"mouse"); ksort($arr, $sort_flags=SORT_FLAG_CASE); var_dump($arr);

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.
