**Course Title:** Modern PHP Development: Best Practices and Advanced Techniques **Section Title:** Final Project and Advanced Topics **Topic:** Start working on the final project that integrates the learned concepts into a full-fledged PHP application. **Objective:** By the end of this lab, you will be able to integrate the concepts learned throughout the course into a comprehensive PHP application, demonstrating your understanding of modern PHP development best practices and advanced techniques. **Introduction:** In this lab, you will apply the knowledge and skills gained throughout the course to create a full-fledged PHP application. This project will challenge you to think critically and develop a well-structured, scalable, and maintainable application. **Prerequisites:** Before starting this lab, ensure you have completed the previous topics and have a solid understanding of: * PHP fundamentals (syntax, variables, data types, control structures, functions, etc.) * Object-Oriented Programming (OOP) in PHP (classes, objects, inheritance, polymorphism, etc.) * Database integration in PHP using PDO (CRUD operations, prepared statements, etc.) * Error handling and exception management * Security best practices in PHP (SQL injection prevention, XSS prevention, CSRF protection, password hashing, etc.) * Modern PHP frameworks (Laravel or Symfony) * Testing in PHP using PHPUnit * Version control with Git and dependency management with Composer **Lab Instructions:** For this lab, you will create a simple e-commerce application that integrates the following features: 1. **User registration and authentication**: Implement user registration, login, and logout functionality using password hashing and secure password storage. 2. **Product management**: Create a database to store products with their details (name, price, description, etc.) and implement CRUD operations for product management. 3. **Shopping cart and order management**: Implement a shopping cart and order management system, allowing users to add products to their cart and place orders. 4. **Payment gateway integration**: Integrate a payment gateway (PayPal, Stripe, etc.) to enable secure payment processing. **Technical Requirements:** * Use a modern PHP framework (Laravel or Symfony) for the project * Implement OOP principles and design patterns * Use PDO for database integration and prepared statements for SQL queries * Implement error handling and exception management using try-catch blocks * Use PHPUnit for unit testing and testing controllers, models, and services * Use Composer for dependency management and version control with Git **Example Code and Resources:** * Laravel Documentation: [https://laravel.com/docs/](https://laravel.com/docs/) * Symfony Documentation: [https://symfony.com/doc](https://symfony.com/doc) * PayPal PHP SDK: [https://github.com/paypal/PayPal-PHP-SDK](https://github.com/paypal/PayPal-PHP-SDK) * Stripe PHP SDK: [https://github.com/stripe/stripe-php](https://github.com/stripe/stripe-php) **Submission Guidelines:** Upon completion of the lab, submit your project code through a link to a GitHub repository or a zip file containing the project files. **Comments and Help:** If you have any questions or need help during the lab, please leave a comment below. I will respond to your comment as soon as possible. **Additional Tips and Best Practices:** * Follow best practices for code organization, naming conventions, and commenting. * Use version control to manage your code changes. * Test your application thoroughly before submission. * Consider implementing additional features, such as user roles, order status management, or product reviews, to make your application more comprehensive.
