<?php $input = array('bar', 'baz'); $res = array_combine($input, $input); $expected = array('bar' => 'bar', 'baz', 'baz'); var_dump($res == $expected);

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).
