run code in 300+ PHP versions simultaneously
<?php $array = [ [1, 30, 33], ['id' => 5] ]; $result = array_reduce($array, function (array $result, array $array) { return array_merge($result, array_map(function ($id) { return compact('id'); }, $array)); }, []); var_dump($result);
Output for git.master, git.master_jit, rfc.property-hooks
array(4) { [0]=> array(1) { ["id"]=> int(1) } [1]=> array(1) { ["id"]=> int(30) } [2]=> array(1) { ["id"]=> int(33) } ["id"]=> array(1) { ["id"]=> int(5) } }
