Object-Oriented PHP

Writing Resilient & Reusable Code in PHP 7

About the Book

Most PHP developers have a clear understanding of what technical debt looks like and the business necessity of having resilient and reliable code. With the release of PHP 7, the Object-Oriented language features of PHP have matured significantly. This book seeks to discuss how you can use Object-Oriented PHP now.

In order to rapidly deliver value through software, your codebase needs to be resilient to the forces of change. This book will guide you through using Object-Orientation in modern PHP to deliver a reliable and reusable code throughout the design, development and construction phases. Whether working on a brand new codebase or refactoring existing code, this book will discuss the patterns to ensuring your codebase is resilient and reliable for years to come.

Topics include:

  • An Introduction to Object-Orientation (Classes, Scalar Type Hinting, Interfaces, Abstract Classes, Inheritance, Coding Standards)
  • Advanced Object-Oriented Programming (Advanced OOP, Magic Methods, Polymorphism, Generators, Composition vs Inheritance, Traits)
  • SOLID Design Principles
