<?php $array = [ [1, 2], [3, 4], ]; foreach ($array as list($a, $a)) { // $a contains the first element of the nested array, // and $b contains the second element. echo "A: $a; B: $b\n"; }

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).
