Professional PHP: Advanced Techniques

The book "Professional PHP: Advanced Techniques" is intended for developers who have already mastered the basics of the language and want to reach a new level of mastery. This is not a textbook for beginners — it is a practical guide to creating complex, scalable, and secure web applications in PHP.

What is this book about?

The author systematically reveals key aspects of professional development:

• Architecture and Design Patterns — SOLID, MVC, Dependency Injection, Repository, Event-Driven, and other patterns applicable in real-world projects.
• Asynchronous Programming — working with ReactPHP, Swoole, generators, and coroutines to create non-blocking applications.
• Performance Optimization — caching (Redis, Memcached, APCu), profiling with Xdebug and Blackfire, optimizing database queries and memory usage.
• Security — protection against XSS, CSRF, SQL injections, session management, data encryption, and safe handling of user input.
• Testing — unit, integration, and functional testing with PHPUnit, Mockery, and Codeception.
• Working with Databases — advanced techniques for working with ORM (Doctrine, Eloquent), migrations, sharding, and replication.
• DevOps Tools — Docker, CI/CD, deployment, and monitoring of PHP applications in production.

Who is this book for?

The book is aimed at:

• PHP developers with 1+ years of experience who want to deepen their knowledge;
• team leads and architects designing complex systems;
• professionals transitioning from "classic" PHP to modern frameworks (Laravel, Symfony, Yii2);
• anyone who wants to write clean, maintainable, and fast code.

What will the reader learn?

• How to design a flexible architecture resistant to changing requirements.
• How to find and eliminate performance bottlenecks.
• How to protect an application from attacks and data leaks.
• How to automate testing and deployment.
• How to effectively work with asynchronous tasks and queues.
• How to use modern tools for profiling and debugging.

The book contains numerous code examples, practical exercises, and references to real-world projects. After studying it, you will be able to confidently take on the development of high-load services and complex enterprise systems in PHP.

"Professional PHP: Advanced Techniques" — this is your next step from "it just works" to "it works efficiently, securely, and scalably."
