This book is not just another syntax tutorial. "PHP: Tips and Best Practices" is a desktop guide that will help you write professional, secure, and high-performance PHP code. The author has compiled years of development experience, saving the reader from common mistakes and demonstrating the right approaches to solving real-world problems.

What is this book about?

The book covers a full range of topics — from the basics of clean code to complex architectural solutions. You will learn:

• How to organize a project structure so that the code is easily readable and maintainable.
• Modern PSR standards and their practical application.
• SOLID principles, design patterns (Factory, Singleton, Repository, Dependency Injection) and when to use them.
• Working with databases: PDO, ORM (Doctrine, Eloquent), writing efficient queries and preventing SQL injections.
• Application security: protection against XSS, CSRF, session hijacking, data validation.
• Performance optimization: caching (OPcache, Redis), profiling, memory management.
• Testing: unit tests (PHPUnit), integration testing, TDD and BDD.
• Working with popular frameworks (Laravel, Symfony) — best practices, not just "how to do it".
• Deployment and CI/CD: Docker, Composer, dependency management.
