从json中删除不需要的数组

I'm new to Laravel. I'm creating a json structure using a function. This is my current output:

{
    "success": "1",
    "data": [
        {
            "category_type_id": 1,
            "category_type": "Study",
            "category_icon": "http://192.168.1.132:8000/images/category/study.svg"
        },
        {
            "category_type_id": 2,
            "category_type": "Sports",
            "category_icon": "http://192.168.1.132:8000/images/category/game.svg"
        },
        {
            "category_type_id": 3,
            "category_type": "Other",
            "category_icon": "http://192.168.1.132:8000/images/category/other.svg"
        }
    ]
}

This is my controller code:

$get_all_category = CategoryType::all();

return response()->json(['success' => '1', 'data' => $get_all_category]);

I want result without array that is started from data plz need solution

Just remove the other attributes from your from your json response:

$get_all_category = CategoryType::all();
return response()->json($get_all_category);

That will return your json like this:

[ 
    { 
        "category_type_id": 1,
        "category_type": "Study",
        "category_icon": "http://192.168.1.132:8000/images/category/study.svg"
    },
    {
        "category_type_id": 2,
        "category_type": "Sports",
        "category_icon": "http://192.168.1.132:8000/images/category/game.svg" },
    {
        "category_type_id": 3
        "category_type": "Other",
        "category_icon": "http://192.168.1.132:8000/images/category/other.svg"
     }
]

If you want to keep the success atribute you can do something like this, but it would just change the old data attribute you want to get rid of to '0':

$get_all_category = CategoryType::all();
return response()->json(['success' =>'1', $get_all_category]);
