multi-dimensional array hierarchy from key name

Question

I like to know how can I get the hierarchy by the identifier Key NAME, just the values with PHP. I already had try some implode functions but without success. I appreciated any help. Thanks
This is an example :

This result would be ok: in array or print in screen line by line.

This should be something like this:

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']);
    }
}

I not on computer so this pseudo code only...

$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;
}
