確定什麼是chlid的水平php

Question

我想獲得父母的孩子關係，併成功得到，但我堅持如何確定什麼是兒童的水平。

這裏是我的代碼

public function getDownline($userid = null) { 
     $category_data = array(); 

     $where = array('parent_id' => $userid); 
     $this->db->where($where); 
     $category_query = $this->db->get('users')->result(); 

     $category_data = array(); 
     foreach ($category_query as $category) { 
      $category_data[$category->id] = array($category); 
      $children = $this->getDownline($category->id); 
      if ($children) { 
       $category_data[$category->id]['children'] = $children; 
      } 
     } 

     return $category_data; 
    } 

下面是我的表結構

我這種格式

[1136] => Array 
     (
      [0] => stdClass Object 
       (
        [id] => 1136 
        [gid] => 4 
        [parent_id] => 1112

      [children] => Array

             ) 

           ) 

         )

，我認爲你應該這樣做讓輸出這裏的對象上下文 等等mething像應工作

class Users_Model extends CI_Model 
{ 

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

     $where = array('parent_id' => $obj->id); 
     $this->db->where($where); 
     $query = $this->db->get('users')->result("User_Object"); 

     foreach ($query as $objUser) 
     { 
      $obj->add($objUser); 
      $this->getDownline($objUser, ($level+1)); 
     } 
     return $obj; 
    } 

    public function downline_income($userId = null, $offset = 0) 
    { 
     $userId = user::id(); 
     $objUser = new User_Object; 
     $objUser->id = $userId; 
     $downline = $this->user->getDownline($objUser); 
    } 
} 


class User_Object 
{ 
    private $children = []; 
    public $level = 0; 

    public function add(User_Object $obj) 
    { 
     $this->children[] = $obj; 
    } 

}
