PHP

function getCartQty()
    {
        if(empty($_SESSION['cart']))
            return 0;
        $qty = array();
        foreach($_SESSION["cart"] as $item){
            $qty[] =  $item['quantity'];
        }
        return array_sum($quantity);
    }

What I have tried:

PHP

function getCartQty()
    {
        if(empty($_SESSION['cart']))
            return 0;
        $qty = array();
        foreach($_SESSION["cart"] as $item){
            $qty[] =  $item['quantity'];
        }
        return array_sum($quantity);
    }

Solution 1

Probably not.
Since $qty is the array you fill from the cart and $quantity is a different variable altogether, it's unlikely that summing it's values will give you the right total ...
