Bugs & Features
<?php $a = array('green', 'red'); $b = array('avocado', 'apple', 'a'); $c = array_combine($a, $b); print_r($c);

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.
