PHP. Objects, Patterns, and Practice

Introduction

Matt Zandstra's book "PHP. Objects, Patterns, and Practice" (original title "PHP Objects, Patterns, and Practice") is one of the most authoritative publications on object-oriented programming in PHP. The sixth edition, released in 2021, covers the latest features of PHP 8, including attributes, named arguments, union types, and much more. The book is aimed at developers who are already familiar with the basics of PHP and want to move to a professional level: master OOP, learn to apply design patterns, and follow best development practices.

What the book is about

The book consists of four parts, each dedicated to a key aspect of professional PHP development:

• Part 1. Objects. A detailed introduction to OOP in PHP: classes, inheritance, interfaces, traits, late static binding, magic methods, and error handling. Special attention is given to modern PHP 8 features.
• Part 2. Patterns. A catalog of classic design patterns (GoF) in the context of PHP: Factory, Singleton, Strategy, Observer, Decorator, Composite, Command, and others. Each pattern is accompanied by practical examples and explanations of when and why to use it.
• Part 3. Practice. Best development practices: testing (PHPUnit), working with databases (PDO, ORM), dependency management (Composer), autoloading, PSR standards, refactoring, working with APIs, and documentation.
• Part 4. Conclusion. An overview of tools and techniques to help maintain code quality: static analysis (PHPStan, Psalm), continuous integration, version control, and deployment.

Who this book is for

This book will be useful for:

• PHP developers who want to deepen their knowledge of OOP and learn to apply design patterns;
• programmers transitioning from procedural to object-oriented style;
• team leads and architects looking to systematize their approach to application design;
• anyone preparing for a Middle/Senior PHP developer interview.

What the reader will learn

• A deep understanding of object-oriented programming in PHP 8;
• The ability to select and implement appropriate design patterns for typical tasks;
• Skills for writing testable, flexible, and maintainable code;
• Practical techniques for working with Composer, PSR-4, PHPUnit, and other tools;
• Methods for refactoring and optimizing existing code;
• Understanding of SOLID principles and their application in real-world projects.

Strengths

• Relevance. The sixth edition is fully revised for PHP 8, making it one of the most up-to-date guides for the language.
• Practical focus. Every theoretical concept is backed by working code examples that can be tried immediately.
• Structure. The book is logically organized: from basic OOP principles to complex patterns and then to best practices.
• Accessible language. The author explains complex concepts in simple and understandable terms, without overloading the text with excessive academic jargon.
• Comprehensive approach. The book covers not only theory but also the tools necessary for professional development (testing, CI/CD, static analysis).

Recommended for

This book is a must-read for all PHP developers striving to reach the next level. It will be useful both for those just starting to learn OOP and for experienced programmers looking to systematize their knowledge of patterns and modern practices. If you write in PHP and want your code to become cleaner, more flexible, and easier to maintain — this book is for you.
