How to move element to another array based from id_item - php

Question

I have a array, but for now, the array is still based on id_order, , like this :
here my controller
public function detail()
{
$data = Order::with('detail')->get();
return $data;
}
result:
[
{
"id": 1, //id_order
"order_number" : "IT.123.76",
"status" : "Pending",
"details" : [
{
"id" : 1,
"id_order" : 1,
"id_item" : 2, //based from this
"name" : "Avocado Juice",
"qty" : 7
},
{
"id" : 2,
"id_order" : 1,
"id_item" : 3, //based from this
"name" : "Orange Juice",
"qty" : 2
},
{
"id" : 3,
"id_order" : 1,
"id_item" : 5, //based from this
"name" : "Mango Juice",
"qty" : 1
}
]
},
{
"id": 2, //id_order
"order_number" : "IT.123.78",
"status" : "Pending",
"details" : [
{
"id" : 4,
"id_order" : 2,
"id_item" : 2, //based from this
"name" : "Avocado Juice",
"qty" : 1
},
{
"id" : 5,
"id_order" : 2,
"id_item" : 9, //based from this
"name" : "Ice Tea",
"qty" : 2
}
]
}
}
]
How to change the structure of the array to be like this(based id_item and name item becomes the key in each element) and also for qty per item calculated, for example = avocado juice has 2 orders, first order has qty: 7 and second order qty: 1 then sums 8 results?
[
{
"qty_total" : 8, // from 7+1 in avocado juice
"Avocado Juice" : [
{
"id" : 1, //From id_order
"id_item" : 2, //Avocado Juice
"order_number" : "IT.123.76",
"qty" : 7
},
{
"id" : 2, //From id_order
"id_item" : 2, //Avocado Juice
"order_number" : "IT.123.78",
"qty" : 1
}
]
},
{
"qty_total" : 2,
"Orange Juice" : [
{
"id" : 1, //From id_order
"id_item" : 3, //Orange Juice
"order_number" : "IT.123.76",
"qty" : 2
}
]
},
{
"qty_total" : 1,
"Mango Juice" : [
{
"id" : 2, //From id_order
"id_item" : 5, //Mango Juice
"order_number" : "IT.123.76", //order_number Id_order 1
"qty" : 1
}
]
},
{
"qty_total" : 2,
"Ice Tea" : [
{
"id" : 1, //From id_order
"id_item" : 9, //Ice Tea
"order_number" : "IT.123.78",
"qty" : 2
}
]
},
]
Thanks for advance

You can try something like this.
const orders = [
{
"id": 1, //id_order
"order_number": "IT.123.76",
"status": "Pending",
"details": [
{
"id": 1,
"id_order": 1,
"id_item": 2, //based from this
"name": "Avocado Juice",
"qty": 7
},
{
"id": 2,
"id_order": 1,
"id_item": 3, //based from this
"name": "Orange Juice",
"qty": 2
},
{
"id": 3,
"id_order": 1,
"id_item": 5, //based from this
"name": "Mango Juice",
"qty": 1
}
]
}, {
"id": 2,
"order_number": "IT.123.78",
"status": "Pending",
"details": [
{
"id": 4,
"id_order": 2,
"id_item": 2, //based from this
"name": "Avocado Juice",
"qty": 1
},
{
"id": 5,
"id_order": 2,
"id_item": 9, //based from this
"name": "Ice Tea",
"qty": 2
}
]
}
];
var ordersById = {};
orders.forEach((order) => {
order.details.forEach((detail) => {
// ToDo: filter out completed/nonpending orders
let orderGroup;
if (!ordersById[detail.id_item]) {
orderGroup = {qty_total: detail.qty};
orderGroup[detail.name] = [{id: detail.id_order, id_item: detail.id_item, order_number: order.order_number, qty: detail.qty}];
ordersById[detail.id_item] = orderGroup;
} else {
orderGroup = ordersById[detail.id_item];
orderGroup.qty_total += detail.qty;
orderGroup[detail.name].push([{id: detail.id_order, id_item: detail.id_item, order_number: order.order_number, qty: detail.qty}]);
}
});
});
const result = Object.keys(ordersById).map((order_id) => { return ordersById[order_id];});;
console.log(result);
