Question

如何压缩多维数组递归php。我试过这个link代码但没有用。我尝试了许多其他链接，但没有工作。 This代码已用于创建此数组。

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;
}

这是我需要展平的阵列。

我尝试使用以下代码，但它仅适用于第2级

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;
}

欲望输出

我不知道为什么你需要做这种复杂的扁平化，我很确定你可以 - // 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)); - 你可以通过以下方式更轻松地完成这项工作，但是你可能需要在这里使用递归，例如：

npm install

P.S 对于大数组而言，递归通常更为昂贵
