i don't know how the cart stores data on the session, but doing in the following way will make it easy.
$cartProducts = array_keys($_SESSION['cart']);
get product details from the DB something like:-
where product_id IN(implode(',',$cartProducts))"
loop through the products got from the DB
$total = 0;
while ($row = mysqli_fetch_assoc($result)){
$subtotal = $row['price'] * ($_SESSION['cart'][$row['id']]['quantity']);
$total += $subtotal;
// now you got product detail, quantity, price
// print the html formatted information here
}
at the end print the $total
if you change the quantity - then update the session cart, and repeat the above.
Note:- it is just an example, you need to add validations, fomat/secure sql etc
