<?php $num1 = "5"; $num2 = "6"; var_dump(get_defined_vars()); var_dump($GLOBALS);

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.
