<?php $data = array('mail' => null, 'bar' => 'baz'); var_dump(array_key_exists('mail', $data));

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.
