Codeigniter：創建結果的多維數組

Question

我想獲得按產品分組的多維數組。

這裏是sql，我曾嘗試：

$sql = "SELECT * from order_detail OD\n" 
    . "LEFT JOIN product as pro ON pro.product_id = OD.product_id\n" 
    . " LEFT JOIN `order` as o ON o.order_id = OD.order_id \n" 
    . "WHERE OD.order_id IN (1,4) AND OD.user_id =2\n" 
    . "group by OD.product_id\n" 
    . "order By OD.Product_ID, OD.Order_ID"; 

這個SQL給出以下結果：

Array 
(
    [0] => Array 
     (
      [order_detail_id] => 1 
      [user_id] => 2 
      [order_id] => 1 
      [product_id] => 13 
      [product_name] => Prodict Test 
     ) 

    [1] => Array 
     (
      [order_detail_id] => 2 
      [user_id] => 2 
      [order_id] => 1 
      [product_id] => 12 
      [product_name] => Product One 
     ) 

    [2] => Array 
     (
      [order_detail_id] => 3 
      [user_id] => 2 
      [order_id] => 1 
      [product_id] => 11 
      [product_name] => Fodod 
     ) 

    [3] => Array 
     (
      [order_detail_id] => 34 
      [user_id] => 2 
      [order_id] => 4 
      [product_id] => 13 
      [product_name] => Prodict Test 
     ) 

    [4] => Array 
     (
      [order_detail_id] => 35 
      [user_id] => 2 
      [order_id] => 4 
      [product_id] => 12 
      [product_name] => Product One1 
     ) 

    [5] => Array 
     (
      [order_detail_id] => 36 
      [user_id] => 2 
      [order_id] => 4 
      [product_id] => 11 
      [product_name] => Fodod 
     ) 

) 

，這是strecture我想：

Array 
     (
      [0] => Array 
       (

        [product_id] => 13 
        [product_name] => Prodict Test 
         ['order'] => Array 
          (
           [0] => Array 
             (
              [order_detail_id] => 1 
              [user_id] => 2 
              [order_id] => 1 
             ) 
           [1] => Array 
             (
              [order_detail_id] => 34 
              [user_id] => 2 
              [order_id] => 4 
             ) 
          ) 
       ) 

      [1] => Array 
        (
         [product_id] => 12 
         [product_name] => Product One 
          ['order'] => Array 
          (
           [0] => Array(
               [order_detail_id] => 2 
               [user_id] => 2 
               [order_id] => 1 
              ) 
           [0] => Array(
               [order_detail_id] => 35 
               [user_id] => 2 
               [order_id] => 4 
              ) 
          ) 
        ) 

     ) 

任何人都可以給我建議我如何完成它？

這裏是我的表strecture

請使用留下了循環協會加盟。使內部循環&加入。 這樣管理您的查詢

$this->db->select('*'); 
$this->db->from('exp_incoming_order'); 
$this->db->order_by('id','desc'); 
$this->db->where('member_id',12); 
$query1 = $this->->db->get(); 
$data=array(); 
foreach($query1->result_array() as $key_1=>$result) 
    { 
    foreach($result as $key=>$value1) 
    { 
     $data[$key_1][$t1][$key]=$value1; 
    } 
} 
foreach($data as $single=>$part) { 
    foreach($tables as $table=>$value2) { 
     $this->db->select('*'); 
     $this->db->from('order_detail'); 
     $this->db->where('order_id',$part['exp_incoming_order']['order_id']); 
     $query2 = $this->db->get(); 
     foreach($query2->result_array() as $key2=>$result2) 
     { 
      foreach($result2 as $key3=>$value3) 
      { 
       $data[$single][$table][$key2][$key3]=$value3; 
      } 
     } 
    } 
}
