根據鍵值拆分數組數組-PHP

Question

用戶提交表單后，我從Post獲得了一個數組。 數據以數組的形式返回給我，但是里面有2個以上的數組和一些屬於父數組的元素。
如何提取父數組中的數組（基於其名稱）並將其余元素添加到新數組中。

array (size=x)
       'parent_array_element1' => string 'value1'
       'parent_array_element2' => string 'value2' 
       'parent_array_element3' => string 'value3' 
       'parent_array_element4' => string 'value4'
       'parent_array_element5' => string 'value5'
       'parent_array_element6' => string 'value6' 
       'parent_array_element7' => string 'value7'
       'parent_array_element8' => string 'value8'
       'parent_array_element9' => string 'value9'
       'parent_array_element10' => string 'value10' 
   'internalArray1' => 
      array 
        'internalArray1_element1' => string 'value1'
        'internalArray1_element2' => string 'value2'
        'internalArray1_element3' => string 'value3'
        'internalArray1_element4' => string 'value4' 
        'internalArray1_element5' => string 'value5' 
        'internalArray1_element6' => string 'value6'
        'internalArray1_element7' => string 'value7'
    'internalArray2' => 
      array
        'internalArray2_element1' => string 'value1'
        'internalArray2_element2' => string 'value2'
        'internalArray2_element3' => string 'value3'
        'internalArray2_element4' => string 'value4'
        'internalArray2_element5' => string 'value5'

到目前為止，我所做的是通過在控制器中執行以下操作來獲取整個數據：

//Gets the parent array (Including nested arrays)
$data = $this->params()->fromPost(); 
//Gets the internaArray1
$data = $this->params()->fromPost('internalArray1'); 
//Gets the internaArray2
$data = $this->params()->fromPost('internalArray2');

但是父數組中有剩余數據，我該如何獲取？

Answer 1

使用unset從父級刪除嵌套數組

//Gets the parent array (Including nested arrays)
$data = $this->params()->fromPost();

//Gets the internalArray1
$internalArray1 = $data['internalArray1'];
//Remove internalArray1 from parent
unset($data['internalArray1']);

//Gets the internalArray2
$internalArray2 = $data['internalArray2'];
//Remove internalArray2 from parent
unset($data['internalArray2']);
