php將節點移動到父數組

Question

如何將'fields'數組的所有節點移動到其父數組'113'，同時取消設置'fields'？

[a] => Array 
    (
     [113] => Array 
      (
       [title] => asdfasdfas 
       [alias] => asdfasdfas 
       [fields] => Array 
        (
         [jr_streetaddress] => Array 
          (
           [type] => text 
           [label] => Street Address 
           [data] => asdfasdffsd 
          ) 

         [jr_towncity] => Array 
          (
           [type] => text 
           [label] => Town/City 
           [data] => Nottingham 
          ) 
        ) 
      ) 
    ) 

Answer 1

假設你的頂級陣列（）是可變$a：

foreach($a as $key => $values){ 
    if(isset($values['fields'])) 
    { 
     $a[$key] = array_merge($a[$key], (array) $values['fields']); 
     unset($a[$key]['fields']); 
    } 
} 

或者，如果您不想擊中$a中的每個數組元素，則可以刪除該循環並用$values替換$a[113]和$key並使用113。

還要注意的領域元素轉換爲數組，僅僅指剛萬一它不是一個與(array) $values['fields']

Answer 2

如果你能夠讓這個陣列是這樣的：

[a] => Array 
(
    [113] => Array 
     (
      [title] => asdfasdfas 
      [alias] => asdfasdfas 
      [jr_streetaddress] => Array 
         (
          [type] => text 
          [label] => Street Address 
          [data] => asdfasdffsd 
         ) 

      [jr_towncity] => Array 
         (
          [type] => text 
          [label] => Town/City 
          [data] => Nottingham 
         ) 
     ) 
) 

嘗試使用此代碼：

$array['a'][113]['jr_streetaddress'] = $array['a'][113]['fields']['jr_streetaddress']; 
$array['a'][113]['jr_towncity'] = $array['a'][113]['fields']['jr_towncity']; 
unset($array['a'][113]['fields']);
