иерархия многомерного массива из имени ключа

Question

Мне хотелось бы узнать, как получить иерархию по идентификатору Key NAME, только значениям с PHP. Я уже пробовал некоторые функции взрыва, но безуспешно. Я оценил любую помощь. Спасибо
Это пример:

$treeArray = (Array
(
    [0] => Array
        (

            [parents] => 
            [children] => Array
                (

                        )

                )

        )

)
);

Этот результат будет в порядке: в массиве или печать на экране строка за строкой.

Answer 1

Это должно быть примерно так:

function rec($arr, $prefix ="") {
    if ($prefix != "") $prefix .= "/";
    foreach($arr as $e) {
        echo $prefix . $e['name'];
        if (!empty($e['children']))
            rec($e['children'], $prefix . $e['name']);
    }
}

Я не на компьютере, поэтому только этот псевдокод ...

Answer 2

$array = [
    ['App', 'Classes', 'Auth'],
    ['App', 'Classes', 'Auth'],
    ['App', 'Classes', 'Middleware'],
    ['App', 'Classes', 'Phone'],
    ['App', 'Classes', 'Auth'],
    ['App', 'Mail'],
    ['App', 'Mail', 'Sender'],
    ['App', 'Box'],
    ['Bla', 'bli'],
];

var_dump(arrayToNamespace($array));

function arrayToNamespace($array) {
    $newArr = array();

    foreach ($array as $nsArr) {
        $wns = &$newArr;
        foreach ($nsArr as $ns) {
            if (!isset($wns[$ns])) {
                $wns[$ns] = array();
            }
            $wns = &$wns[$ns];
        }
    }
    return $newArr;
}
