創建相同的密鑰值不同

Question

我需要重新創建一個數組的數組中結合相同的密鑰和puting 在他們的價值觀..ok其並不清楚，這裏是一個形而下爲例數組：

我有這樣的陣列1波紋管：

Array1 
(
    [0] => Array 
     (
      [profile_field_id] => 214 
      [value] => 1 
      [order] => 1 
     ) 

    [1] => Array 
     (
      [profile_field_id] => 214 
      [value] => 2 
      [order] => 2 
     ) 

    [2] => Array 
     (
      [profile_field_id] => 214 
      [value] => 4 
      [order] => 3 
     ) 

    [3] => Array 
     (
      [profile_field_id] => 214 
      [value] => 8 
      [order] => 4 
     ) 

    [4] => Array 
     (
      [profile_field_id] => 215 
      [value] => 1 
      [order] => 1 
     ) 

    [5] => Array 
     (
      [profile_field_id] => 215 
      [value] => 2 
      [order] => 2 
     ) 

，我需要建立在array1數組，輸出應該是：

Array 
(
    [214] => Array 
     (

      [value] => Array 
      (
      [1] 
      [2] 
      [4] 
      [8] 

      ) 

     ) 

    [215] => Array 
     (
      [value] => Array 
      (
      [1] 
      [2] 


      ) 
     ) 

感謝您的幫助， 個傑斯

Answer 1

我認爲這是你在找什麼：

$array2 = array();                 
foreach($array1 as $key => $value)             
{                     
    $array2[$value['profile_field_id']]['value'][$value['value']] = $value['value'];                                                            
} 

與您的數據集，它輸出這對我來說：

Array 
( 
    [214] => Array 
     ( 
      [value] => Array 
       ( 
        [1] => 1 
        [2] => 2 
        [4] => 4 
        [8] => 8 
       ) 

     ) 

    [215] => Array 
     ( 
      [value] => Array 
       ( 
        [1] => 1 
        [2] => 2 
       ) 

     ) 

) 

要將輸出從相同的鍵/值更改對，從作業左側刪除第一個$ value ['value']。
