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