Why my structure of collection is not expected (not as I need) - php

Question

I have the following method of my cart class:
public function add($productId) {
$product = Product::where('id', $productId)->first();
if (!$product) {
return false;
}
if ($this->items->has($productId)) {
$this->items->$productId->qty++;
} else {
$this->items->push([$productId => [
'name' => $product->title,
'price' => $product->price,
'is_sale' => $product->is_sale,
'sale_price' => $product->sale_price,
'sale_percent' => $product->sale_percent,
'can_use_promocode' => $product->can_use_promocode,
'qty' => 1,
]
]);
}
$this->save();
return true;
}
But on dump($cart) in controller, I got this:
+items: Collection {#176 ▼
#items: array:1 [▼
0 => {#171 ▼
+"2": {#164 ▼
+"name": "101 роза"
+"price": 4999
+"is_sale": 0
+"sale_price": null
+"sale_percent": null
+"can_use_promocode": 1
+"qty": 1
}
}
]
}
But I need to:
+items: Collection {#176 ▼
#items: array:1 [▼
2 => {
+"name": "101 роза"
+"price": 4999
+"is_sale": 0
+"sale_price": null
+"sale_percent": null
+"can_use_promocode": 1
+"qty": 1
}
]
}
In this case, I thought that $this->items->push([$productId => ...] will push the key => value pair to collection, but collection creates its own pair, and my pair goes into collection pair. (idk how to describe it correctly, but I think you understand me :) )

Answer 1

Use the put() method instead:
->put($key, $data)
The put method sets the given key and value in the collection
