Building PHP applications using domain-driven design (DDD) techniques results in code that is easier to modify, maintain, test, and makes for a better user experience. In this hands-on tutorial, you will become versed in the best practices for solving problems using domain-driven design in PHP from start to finish.

You will learn to:

• Discover a ubiquitous language and identify changes in the design of PHP classes, methods, and problem solving
• Assemble an incorruptible domain model in PHP by encapsulating business logic in immutable value objects, specifications, and entities
• Employ best practices for persisting and accessing entities and aggregate roots in Doctrine and Zend DB and Hydrator
• Use advanced PHP object-oriented techniques to simplify code and reduce state complexity
• Plan for change by using the Hexagonal Architecture Pattern
