Laravel group by multiple level - mysql

Question

How to GROUP BY multiple levels in Laravel. I've tried this code.
I've also used toArray() then array_values(), but same result as using values()
EDIT: Sorry, I wrote value() instead of values()
When using values(), product_name not showing.
// Controller
$products = DB::table('product_registrations')
// ->select(['product_name', 'color'])
->join('colors', 'colors.id', '=', 'product_registrations.color_id')
->join('sizes', 'sizes.id', '=', 'product_registrations.size_id')
->join('products', 'products.id', '=', 'product_registrations.product_id')
->get()
->groupBy(['product_name', 'color']);
// ->values(); // I've used values(), it worked but first level groupBy name missing
return response()->json(['products' => $products]);
---
I want something like:
products: [
product1: [
color1: {},
color2: {}
]
]
Without values()
{
"products": {
"light blue dress": {
"Ягаан": [
{
"id": 1,
"product_id": 1,
"color_id": 1,
"size_id": 6,
"color": "Ягаан",
"product_name": "light blue dress",
}
],
},
}
}
With values()
{
"products": [
{
"Ягаан": [
{
"id": 1,
"product_id": 1,
"color_id": 1,
"size_id": 6,
"color": "Ягаан",
"product_name": "light blue dress",
}
],
}
]
}

Try this one. I also have problem on this last week but I manage to get through.
$products::latest()->get();
$products = products->groupBy(function($product) {
return $product->name;
});
$products = products->map(function($product) {
return $product->groupBy(function($prod) {
return $prod->color;
});
});
return $products;
You can also optimize this method by using array_only this method is only for laravel
