PHP: Tips and Best Practices — From Beginner to Professional

The book "PHP: Tips and Best Practices" is not just another syntax tutorial, but a practical guide that will help you transition from writing "working" code to creating professional, maintainable, and secure software in PHP.

The author, Alexey Smirnov, a senior developer with 10 years of experience, has compiled in one book time-tested methodologies used in large projects (from frameworks to high-load services). The book is structured on the "from simple to complex" principle: each chapter contains specific examples, typical mistakes, and ways to fix them.

Who is this book for?

• Beginning PHP developers who already know the basics of the language and want to write code they won't be ashamed to show colleagues.
• Experienced programmers looking to systematize their knowledge and learn modern approaches (PSR-12, SOLID, design patterns).
• Team leads and architects seeking clear code review criteria and standards for their team.

What will you learn from the book?

• How to organize project structure: naming, autoloading (Composer), namespaces.
• Basics of object-oriented programming in PHP: encapsulation, inheritance, polymorphism with real-world examples.
• Working with databases: PDO, prepared statements, protection against SQL injection.
• Security: data validation, XSS, CSRF, working with passwords (password_hash, password_verify).
• Performance optimization: caching (APCu, Redis), profiling (Xdebug), memory management.
• Testing: unit tests (PHPUnit), integration testing, TDD.
• Modern standards: PSR-1, PSR-4, PSR-12, dependency injection (DI containers).
• Working with APIs: creating RESTful services, error handling, logging (Monolog).

Special attention is given to PHP "pitfalls": non-obvious function behavior, type issues, vulnerabilities in popular libraries. Each tip is accompanied by "before" and "after" code so you can immediately see the difference.

The book is written in a lively language, without excessive academicism. You won't find dry theory here — only what is truly useful in practice. After reading, you will be able to confidently participate in code reviews, write easily maintainable code, and avoid typical mistakes that slow down development.

Whether you work with Laravel, Symfony, or write your own engine, the principles described in this book are universal. This is a must-read for anyone who wants to become a sought-after PHP developer.
