<?php $promos = [ '123' => ['weight' => 1], '234' => ['weight' => 3], '345' => ['weight' => 2], ]; var_dump(array_column($promos, 'weight', $promos));

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.
