<?php $one = [ "one" => [ "rawr1" => "sweet1" ], "two" => [ "rawr2" => "sweet2" ], "three" => [ "rawr3" => "sweet3" ] ]; $keys = ["one", "three"]; var_dump(array_intersect_key($one, $keys))

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).
