<?php $a = array( 0 => "apple", "b" => "banana", 3 => "cow", "wrench" => "duck" ); $b = array_intersect_key($a, array_flip(array_filter(array_keys($a), 'is_string'))); var_dump($b);

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).
