How to return an int variable from controller to view in Laravel?

I have created a global variable in my CartController for the quantity of an item, here is the declaration:

class CartController extends Controller
{
    // defining global quantity variable
    private $quantity = 1;

Then in my index() function on the same controller, where I return the view, I pass through the quantity variable like so:

public function index()
{
    $this->quantity;
    return view('cart.cart', ['quantity' => $this]);
}

But when I call it in the cart.blade.php file like this:

<div class="display-quantity">
    {{-- Shows Quantity --}}
    <span class="item-quantity" id="item-quantity">{{ $quantity }}</span>
</div>

It gives me the following error:

TypeError
htmlspecialchars(): Argument #1 ($string) must be of type string, App\Http\Controllers\CartController given (View: /Users/rosscurrie/mobile-mastery-latest/resources/views/cart/cart.blade.php)

enter image description here

I think I need to convert it to a string but I need to work with it as an integer so how do I get around this? Thanks!

It look like you're passing in $this as the quantity.

Try changing your controller's index() code to something like:

public function index()
{
    $myQuantity = $this->quantity;
    return view('cart.cart', ['quantity' => $myQuantity]);
}

It looks like the confusion here is with the -> operator which in php is used to call on object's method or access an object's property the same way . works in Javascript. This statement $this->quantity; accesses the quantity property of $this, so to use it - you need to assign it to a variable (or use it directly). This would have also worked:

public function index()
{
    return view('cart.cart', ['quantity' => $this->quantity]);
}

You can always do things like dd($this->quantity); to ensure you are working with the correct information.
