A simple and flexible shopping cart implementation in PHP using Object-Oriented Programming (OOP) principles. This project demonstrates clean code architecture and is designed to be easily extendable for real-world applications.

• Add, update, and remove items from the shopping cart.
• Item quantity management to reflect user requirements.
• Cart total calculation based on item prices and quantities.
• Object-Oriented Design for clean, maintainable, and reusable code.

• PHP 7.4 or later
• A web server (e.g., Apache, Nginx)
• Composer (optional for dependency management)

1. Clone the repository:

   git clone https://github.com/yaouba/php-oop-shopping-cart.git
   cd php-oop-shopping-cart

2. Configure your server: Ensure your web server is pointing to the project directory.

3. Run the application: Open your web browser and navigate to http://localhost/php-oop-shopping-cart or your server URL.

Use the Cart class to add items by specifying the item details (e.g., ID, name, price, and quantity).

$cart = new Cart();
$cart->addItem(new Item(1, 'Apple', 2.99, 3));

You can retrieve and display all items in the cart:

foreach ($cart->getItems() as $item) {
    echo $item->getName() . " - " . $item->getPrice();
}

Get the total cost of items in the cart:

echo "Total: " . $cart->getTotal();

Remove items from the cart by their ID:

$cart->removeItem(1);

• Cart.php: The main class managing cart operations.
• Item.php: A class representing individual cart items.
• index.php: Example usage and testing of the shopping cart functionality.

Contributions are welcome! Feel free to open issues or submit pull requests to improve the project.
