How to disable array sorting?

Question

Yii

Hello, I have such a problem, I change the number of goods with ajaxom, everything works, but the array is sorted according to itself as it wants,
I take the goods from the session according to this orderby for the base, it did not help
this first state

after changing the number of goods, it turns out, the goods that were on 1 ohm place now on 3 ohm

it's buttons

<div class="input-group">
                            <input id="<?= $id ?>"  type="text" class="form-control input-number quantity" value="<?= $item['qty'] ?>">
                            <a href="cart" data-id="<?= $id ?>" class="btn btn-default addd"><i class="fas fa-sync"></i></a>
                        </div>

this is an ajax request

$('.addd').on('click', function () {
        var id = $(this).data('id');
        qty = $('input[id=' + id + ']').val();
        $.ajax({
            url: '/site/addd',
            data: {id: id , qty: qty},
            type: 'GET'
        });
    });

this is a function

public function actionAddd()
    {
        $id = Yii::$app->request->get('id');
        $qty = (int)Yii::$app->request->get('qty');
        $qty = !$qty ? 1 : $qty;
        $product = Products::findOne($id);
        if(empty($product)) return false;
        $session = Yii::$app->session;
        $session->open();
        $cart = new Cart();
        $cart->recalc($id);
        $cart->addToCart($product, $qty);
        return $this->render('cart', compact('session'));
    }

what is the problem ?(

Answer 1

By turning on psychic abilities:
or
if sorting and output to us in php, and the goods in the session are in some specific order, then
order by field(`id`,7, 12, 4) # your id order
or if the list output is in js,
see js array before output, perhaps the keys are id, so it is necessary to apply array_values ​​before output to json

Answer 2

If you output some data to the page in JSON, then any arrays that have numeric keys will be sorted by these keys. Regardless of how you sorted them before JSON was formed.
The easiest way is not to use arrays with keys in principle. Need id - make it a property, not a key. And everything will reach the page in the same order in which you created it. If they are not needed at all, output array_values ​​in JSON, as already mentioned.
