Professional PHP: Advanced Techniques

The book "Professional PHP: Advanced Techniques" is a practical guide for developers who have already mastered the basics of the PHP language and want to move to the next level. The author, Alexey Voronov, shares years of experience in creating complex, scalable, and maintainable web applications. The book is not overloaded with basic theory — it focuses on real-world tasks that a senior developer faces in a production environment.

What is this book about?

This is not another reference book on PHP functions. It is a deep dive into professional development. You will learn:

• How to apply creational, structural, and behavioral design patterns (Singleton, Factory, Observer, Strategy, and others) in the context of PHP;
• How to build clean architecture adhering to SOLID and GRASP principles;
• How to work with PSR standards (PSR-4, PSR-7, PSR-11, PSR-14) and write interoperable code;
• How to implement automated testing: unit tests with PHPUnit, integration tests, mock objects, and TDD;
• How to optimize performance: caching (OPcache, Redis), profiling (Xdebug, Blackfire), working with queues (RabbitMQ, Gearman);
• How to design high-load systems: asynchronous tasks, database sharding, horizontal scaling;
• How to work with modern frameworks (Laravel, Symfony) at the core level: service containers, middleware, event-driven architecture.

Who is this book for?

• PHP developers with 2+ years of experience who want to systematize their knowledge and advance to the senior level;
• Backend engineers transitioning from other languages (Java, C#, Python) to PHP;
• Tech Leads and architects looking for practical examples of building complex PHP systems.

What will you gain after reading?

• Confident mastery of advanced PHP 8.x techniques (attributes, named arguments, match expressions, readonly properties);
• Skills for refactoring legacy code without the risk of "breaking" the project;
• Understanding how to design APIs (REST, GraphQL) with security and performance in mind;
• Ready-made templates for organizing code in large teams.

Each chapter contains code from real projects, class diagrams, and self-assessment exercises. The book is suitable both for self-study and for preparing for interviews at large IT companies.

"Professional PHP: Advanced Techniques" is your guide to the world of modern PHP. After reading it, you will stop writing "just working code" and start creating reliable, testable, and scalable systems.
