无法访问合并数组的元素

Question

所以我有两个需要一起工作的对象，其中一个想法是合并它们。这样做了，使用了array_merge，但是现在我无法从合并的对象访问第二个对象，而且我被困住了。合并后出现的键看起来有点奇怪，我用错了吗？

$merged=array_merge_recursive((array)$post,(array)$image);

var_dump for $merged向我展示了以下内容：

array (size=10)
  0 => 
    object(Models\Post)[7]
      protected 'id' => string '17' (length=2)
      protected 'title' => string 'qwq' (length=3)
      protected 'body' => string 'wqwq' (length=4)
      protected 'views' => string '22' (length=2)
      protected 'imgId' => string '17' (length=2)
      protected '_attr_accessible' => 
        array (size=3)
          0 => string 'title' (length=5)
          1 => string 'body' (length=4)
          2 => string 'views' (length=5)
      protected '_validators' => 
        array (size=0)
          empty
      protected '_errors' => 
        array (size=0)
          empty
      protected '_valid' => boolean true
  '�*�id' => string '17' (length=2)
  '�*�path' => string '/media/' (length=7)
  '�*�name' => string 'col_right_callout.jpg' (length=21)
  '�*�idPost' => string '0' (length=1)
  '�*�description' => string 'wqeqw' (length=5)
  '�*�_attr_accessible' => 
    array (size=3)
      0 => string 'name' (length=4)
      1 => string 'path' (length=4)
      2 => string 'description' (length=11)
  '�*�_validators' => 
    array (size=0)
      empty
  '�*�_errors' => 
    array (size=0)
      empty
  '�*�_valid' => boolean true

如何从数组的第二部分访问路径或任何字段？$post含量

array (size=1)   0 => 
    object(Models\Post)[7]
      protected 'id' => string '17' (length=2)
      protected 'title' => string 'qwq' (length=3)
      protected 'body' => string 'wqwq' (length=4)
      protected 'views' => string '23' (length=2)
      protected 'imgId' => string '17' (length=2)
      protected '_attr_accessible' => 
        array (size=3)
          0 => string 'title' (length=5)
          1 => string 'body' (length=4)
          2 => string 'views' (length=5)
      protected '_validators' => 
        array (size=0)
          empty
      protected '_errors' => 
        array (size=0)
          empty
      protected '_valid' => boolean true

$image含量

object(Models\Image)[9]
  protected 'id' => string '17' (length=2)
  protected 'path' => string '/media/' (length=7)
  protected 'name' => string 'col_right_callout.jpg' (length=21)
  protected 'idPost' => string '0' (length=1)
  protected 'description' => string 'wqeqw' (length=5)
  protected '_attr_accessible' => 
    array (size=3)
      0 => string 'name' (length=4)
      1 => string 'path' (length=4)
      2 => string 'description' (length=11)
  protected '_validators' => 
    array (size=0)
      empty
  protected '_errors' => 
    array (size=0)
      empty
  protected '_valid' => boolean true

由于图像是对象，所以在将对象转换为数组时，受保护的私有属性具有特殊字符。

使用post，您将数组转换为数组。如果您执行类似于(数组)$post的操作，那么两个对象都会遇到相同的问题。
