函數來創建可摺疊的print_r（）var_dump（）？

Question

你可能已經熟悉了print_r的輸出：

Hierarchy Object 
(
    [parent:private] => Hierarchy Object 
     (
      [parent:private] => 
      [children:private] => Array 
       (
       ) 

      [level:private] => 0 
      [price_modes:private] => Array 
       (
       ) 

      [id:protected] => 
      [left_id:protected] => 
      [right_id:protected] => 
      [name:protected] => 
      [validationFailures:protected] => Array 
       (
       ) 

      [_new:private] => 1 
      [_deleted:private] => 
      [modifiedColumns:protected] => Array 
       (
       ) 

     ) 

    [level:private] => 1 
    [price_modes:private] => Array 
     (
     ) 
) 

有什麼，存在會產生HTML將允許我滾了，比方說，家長的東西是這樣的：

Hierarchy Object 
(
    + [parent:private] => Hierarchy Object 
    [level:private] => 1 
) 

然後通過點擊+？重新展開它。
