A shopping cart application will have a catalog to showcase products as a gallery. The products can be stored in a database, file or any other forms as suitable to your business depending on the product list count.
We have already seen many shopping cart example with the database to store products. In a persistent shopping cart example, we have used database tables to manage cart. If we want to sell a huge volume of products, we need database-like storage medium.
Otherwise if count of products is lesser, we can simply manage products in a static way or by using files or arrays. Let us create a shopping cart application without a database by managing products using PHP array.
View Demo
I have created a Product class to define the product array and a function to return this array. I get the product by using this class and display them in a gallery.
This screenshot shows the output of the shopping cart example without a database. It shows tick mark on a product cart to represent that it is currently added to the cart session.
After page refresh, this tick mark will go and we can add more products to the cart.
The gallery will contain the add-to-cart option for each product. After adding a product to the cart, it will be maintained in a PHP session indexed by the product code. The cart item in the session array will be listed to the user.
The cart view contains individual cart delete and bulk delete actions. All the cart action are performed by using jQuery AJAX.
Product Gallery and Cart HTML
I have designed the landing page with two main sections for the products and the cart. I iterate the product array and display each product in a card to showcase all the products in a gallery view.
If the cart session is not empty, I run a loop through the PHP cart session array to display the list of cart items. The HTML code is,

Get Product Array and Create Gallery
In the following code block, the Product class instance is created to get the product array. After getting the product array it is iterated to display each product card.
The card element is marked with the product code to refer the product identity while performing the cart actions.
