<?php $a = [ 'key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', ]; $b = ['key1', 'key3', 'key5']; $c = array_intersect_key($a, array_flip($b)); print_r($c);

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).
