<?php $foo = ['bar' => 'boo']; $baz = ['boo' => 'bay']; $bar = $baz[$foo['bar'] ?? ''] ?? '' ; var_dump($bar); $foo = []; $baz = []; $bar = $baz[$foo['bar'] ?? ''] ?? '' ; var_dump($bar);

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).
