How to respond data with an array instead of object - laravel

Question

I want to receive an array for data, something like this:
"data": [
"6": {
"title": "..",
"photo": ..
}
]
But I am receving an object :
"data": {
"6": {
"title": "..",
"photo": ".."
}
}
And another intresting fact is that for first page I am receiving how it is needed:
"data": [
"1": {
"title": "..",
"photo": ..
},
.
.
.
"6": {
"title": "..",
"photo": ..
}
]
This is my function in controller:
$lists = [];
$cooks = cook::all();
foreach ($cooks as $cook) {
$list = [
'title' => $cook->title,
'photo' => $cook->photos->path,
'recipe' => $cook->recipe->description
];
$lists[] = $list;
}
$collection = $this->paginate($lists, $perPage = 6, $page = null, $options = []);
return new mainCollection($collection);
I have the following function for pagination:
public function paginate($items, $perPage = 15, $page = null, $options = [])
{
$page = $page ?: (Paginator::resolveCurrentPage() ?: 1);
$items = $items instanceof Collection ? $items : Collection::make($items);
return new LengthAwarePaginator($items->forPage($page, $perPage), $items->count(), $perPage, $page, $options);
}
and the following is my resourceColection(mainColection) :
public function toArray($request)
{
return [
'data' => $this->collection,
'meta' => ['pagination' => $this->pagination]
];
}

You can use laravel map since you're working with collections.
$array = $this->collection->map(function ($item, $key) {
return [
'title': "tort",
...
]
});
and encode it as json
public function toArray($request)
{
return [
'data' => json_encode($array),
'meta' => ['pagination' => $this->pagination]
];
}
also you read the documentation here: https://laravel.com/docs/5.8/collections
