<?php $keys = ['a','b','c','d','e','f','g','h','i','z']; $private = [ 'a','b','c','d' ]; $aliases = [ 'z' => 'a' ]; print_r(array_intersect(array_flip($aliases), $private));

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).
