如何在php中获取带有时隙的未来7天数据

Question

我正在codeigniter中使用api's，我有两个表，我想在30分钟内获取接下来7天的数据（无论商店是否已预订）

我的第一个表是“ additional_info”

id  shop_id     shop_open_time  shop_close_time
1   3           09:00:00        22:00:00

第二张表是“预订”

id      user_id     shop_id     service_id      duration(in minutes)    services_dates      start_time      end_time
1       2           3           1               20                      2019-03-26          09:01:10        10:00:00

现在我希望每隔30分钟（无论是否预定时间）有一个商店ID的时隙（以他的营业时间开始，以关闭时间为准）

换句话说，现在我想要类似的结果

{
    "Status": true,
    "Result": {
        "id": "4",
        "salon_id": "3",
        "shop_open_time": "09:00:00.000000",
        "shop_close_time": "22:00:00.000000",
       "availability": [
            {
                "id": 1,
                "date": "27-Mar-2019",
                "arrTimeSlots": [
                    {
                        "id": 1,
                        "time": "09:00 AM",
                        "alreadyBooked": false
                    },
                    {
                        "id": 2,
                        "time": "09:30 AM",
                        "alreadyBooked": false
                    },
                    .....
            {
                "id": 2,
                "date": "28-Mar-2019",
                "arrTimeSlots": [
                    {
                        "id": 1,
                        "time": "09:00 AM",
                        "alreadyBooked": false
                    },
                    {
                        "id": 2,
                        "time": "09:30 AM",
                        "alreadyBooked": false
                    },
                    {
                        "id": 3,
                        "time": "10:00 AM",
                        "alreadyBooked": false
                    },
                    {
                        "id": 4,
                        "time": "10:30 AM",
                        "alreadyBooked": false
                    },
                ....
                //next 5 days
                ...

我尝试使用以下代码，但是得到了错误的数据，我正在获取存储在数据库中的该日期的数据，但是我想检查当前日期到未来6天的时间，这是我的代码
