Develop elegant and rock-solid systems using PHP, aided by three key elements: object fundamentals, design principles, and best practices. Now in its seventh 7th edition, this book has been fully updated for PHP 8.3 and split into two volumes to better accommodate its wealth of new content. Volume 1 covers objects and patterns, while Volume 2 focuses on tools and best practices.

You’ll begin this volume by reviewing PHP’s object-oriented features and other key topics such as class declarations, inheritance, and reflection. The second part of the book is devoted to design patterns. It explains the principles that make patterns powerful and covers many of the classic design patterns, including enterprise and database patterns.

This volume provides a solid grounding in PHP’s support for objects and builds on this foundation to apply the core principles of software design. This includes read only classes, enumerations, typed class constants, as well as various additions to argument and return types.  The knowledge gained from this book will help you master the object-oriented enhancements and the design patterns available for PHP 8, paving the way for developing best practices in Volume 2.
