Group Laravel collection by the given key

In Laravel I want to change response if same user array have multiple response.

I get a response with this function:

controller.php

public function index(){
    $reports = Report::all();
    return $this->sendResponse($reports->toArray(), 'User Reports successfully.');
}

This is my response:

{
    "success": true,
    "data": [
        {
            "id": 66,
            "cuid": 20,
            "name": "my1",
            "created_at": "2018-03-09 00:00:00",
            "updated_at": "2018-03-09 00:00:00",
            "time": "07:19 PM",
            "status": "D"
        },
        {
            "id": 65,
            "cuid": 20,
            "name": "my1",
            "created_at": "2018-03-07 00:00:00",
            "updated_at": "2018-03-07 00:00:00",
            "time": "07:39 PM",
            "status": "D"
        },
        {
            "id": 64,
            "cuid": 21,
            "name": "my2",
            "created_at": "2018-03-02 00:00:00",
            "updated_at": "2018-03-05 00:00:00",
            "time": "07:01 PM",
            "status": "D"
        },
        {
            "id": 63,
            "cuid": 20,
            "name": "my2",
            "created_at": "2018-03-02 00:00:00",
            "updated_at": "2018-03-02 00:00:00",
            "time": "06:44 PM",
            "status": "D"
        }     
    ],
    "message": "User Reportsssss successfully."
}

This is fine my problem is I have 4 array with 2 user instead showing that way I want to show like this:

{
    "success": true,
    "data": [
        my1:{
                {
                    "id": 66,
                    "cuid": 20,
                    "name": "my1",
                    "created_at": "2018-03-09 00:00:00",
                    "updated_at": "2018-03-09 00:00:00",
                    "time": "07:19 PM",
                    "status": "D"
                }
                {
                    "id": 65,
                    "cuid": 20,
                    "name": "my1",
                    "created_at": "2018-03-07 00:00:00",
                    "updated_at": "2018-03-07 00:00:00",
                    "time": "07:39 PM",
                    "status": "D"
                }
        },
         my2:{
                {
                    "id": 63,
                    "cuid": 21,
                    "name": "my2",
                    "created_at": "2018-03-07 00:00:00",
                    "updated_at": "2018-03-07 00:00:00",
                    "time": "07:39 PM",
                    "status": "D"
                }
                {
                    "id": 64,
                    "cuid": 21,
                    "name": "my2",
                    "created_at": "2018-03-02 00:00:00",
                    "updated_at": "2018-03-05 00:00:00",
                    "time": "07:01 PM",
                    "status": "D"
                }
        }
    ],
    "message": "User Reportsssss successfully."
}

How to achive this if same user comes under single array.

The ideal way to do this would be by using collection pipelines. Your original controller method would become the following;

public function index(){
    $reports = Report::all();
    return $this->sendResponse($reports->groupBy('name')->toArray(), 'User Reports successfully.');
}

The groupBy method will split the collection results out into other collections, grouped by the provided column. Because the toArray() method cascades, you'll get a nice array back.
