函数来创建可折叠的打印\u r()var\u dump()?

您可能已经熟悉print\r的输出:

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
        (
        )
)

有没有什么东西可以生成HTML,让我把父级的东西汇总成这样:

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

然后点击+?
