## Overview

This is a PHP/MySQL video-game storefront. A shopper opens the catalog, which loads products and offers add-to-cart; the cart page displays items and handles quantity updates and removal. Controllers translate database rows for the views, while model functions perform catalog and cart queries through a shared connection to MySQL/MariaDB. The README also documents product images and shared styling. Relationships shown here are limited to calls and references visible in the excerpts; the database schema and image assets were not sampled.

Main entry points: [`view/products.php`](https://github.com/torlaw1692/php-ecommerce-app/blob/main/view/products.php) (Product catalog), [`view/cart.php`](https://github.com/torlaw1692/php-ecommerce-app/blob/main/view/cart.php) (Shopping cart), [`controller/cart_controller.php`](https://github.com/torlaw1692/php-ecommerce-app/blob/main/controller/cart_controller.php) (Cart controller), [`model/database.php`](https://github.com/torlaw1692/php-ecommerce-app/blob/main/model/database.php) (Connection config)
