<?php $array = [['user1' => 20], ['user2' => 30], 3 => ['user3' => 10]]; echo array_reduce( $array, fn($result, $row) => $result + current($row), 0 ); echo "\n---\n"; array_walk_recursive($array, function($v)use(&$sum){ $sum += $v; }); // visit each leafnode, increase the $sum tally echo $sum; echo "\n---\n"; $total = 0; // without this declaration, you will generate: "Notice: Undefined variable" foreach ($array as $subarray) { foreach ($subarray as $v) { $total += $v; } } echo $total;

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).
