如何安排父子数组值？

Question

我想安排从子到父的数组值，例如假设我有一个父数组A和B，A＆amp; B也有子数组，如X（A的子）和Y，Z（B的子），所以我希望X在父数组A和Y下的所有细节，Z所有细节父数组B.

以下是我的数组

{
    "status": 200,
    "message": "Success",
    "child": {
        "Parent": [
            {
                "df_cat_id": "3",
                "df_cat_name": "Food",
                "df_cat_image": "44ce23c62a6606de37dfb1a951766ad3.png",

            },

            }
        ],
        "childData": [
            [
                {
                    "df_scat_id": "1",
                    "parent_cat_id": "3",

                    "update_date": "2018-01-18 09:57:17"
                },
                {
                    "df_scat_id": "4",
                    "parent_cat_id": "3",

                    "update_date": "2018-01-18 11:21:09"
                }
            ],
            [
                {
                    "df_scat_id": "5",
                    "parent_cat_id": "5",
                    "df_scat_name": "Beauty Parlor",

                    "update_date": "2018-01-22 09:37:32"
                }
            ]
        ]
    }
}

我想按照以下方式输出..
