Working with laravel collection methods on a Shopping Cart

This is how my collection looks like right now. 

[{"id":"1","quantity":1},{"id":"2","quantity":1}]

What can I do to match the id and change the quantity to 2. This is for a shopping cart.

So in the end it would look like this if we found a item already in cart.

[{"id":"1","quantity":2},{"id":"2","quantity":1}]

You can use collection's transform method. It iterates over the items in the collection, allowing you to change values.

Let's say your collection of objects is stored in $someCollection. You could do this:

$someCollection->transform(function ($item, $key) use ($id) {
    if ($item->id == $id) {
       $item->quantity++;
    }
    return $item;
});

This will increase the quantity by one for the item with the id that you pass in $id

use transform on cart collection.

$id = 1;
$cart->transform(function ($item) use ($id) {
    if ($item['id'] == $id) {
        $item['q']++;
    }
    return $item;
});
