выровнять многомерный массив рекурсивного переполнения стека

Как сгладить рекурсивный многомерный массив php.
Я пробовал с этим ссылка на сайт код, но не работает. Я пробовал много других ссылок, но не работает. это код был использован для создания этого массива.

public function downline_income($userId = null, $offset = 0) {
$userId = user::id();
$limit = AZ::setting('record_per_page');
$objUser = new stdClass();
$objUser->id = $userId;
$downline = $this->user->getDownline($objUser);

AZ::layout('left-content', array(
'block' => 'account/downline_income',
'user' => $userId,
'total_users' => $total_users,
'pagination' => $pagination,
'q' => $userId,
'data' => $downline,
'offset' => $offset,
));
}

public function getDownline($obj, $level = 0) {
$obj->level = $level;

$where = array('parent_id' => $obj->id);
$this->db->select('users.*');
$this->db->where($where);

$query = $this->db->get('users')->result();

foreach ($query as $objUser) {
$obj->data[] = $this->getDownline($objUser, ($level + 1));
}

return $obj;
}

Вот массив, который мне нужно сплющить.

Я пытался с приведенным ниже кодом, но он работает только для уровня 2

public function array_flatten($array, $i = 0) {
$flat = array();

foreach ($array as $value) {
if (isset($value->data) && is_array($value->data)) {
$flat = array_merge($flat, $this->array_flatten($value->data));
} else {
$flat[] = $value;
}
}
return $flat;
}

Я не знаю, почему вам нужно сделать это сложное флаттинг, и я уверен, что вы можете —as it's seems that you are fetching data from database— что вы можете сделать это проще, чем следующим образом, однако вам может понадобиться использовать здесь рекурсию, например:

// Sample data
$arr = [
['level' => 1, 'data' => [['level' => 2],['level' => 3, 'data' => [['level' => 6]]]]],
['level' => 4],
['level' => 9, 'data' => [['level' => 8]]],
];

function flat($data, &$list = [])
{
foreach ($data as $key => $value) {
if (isset($value['data']) && is_array($value['data'])) {
$tmp = $value['data'];
unset($value['data']);
flat($tmp, $list);
}
$list[] = $value;
}
return $list;
}

print_r(flat($arr));

P.S часто рекурсия дороже с большими массивами
