Domain-Driven Design in PHP

Overview of this book

Domain-Driven Design (DDD) has arrived in the PHP community, but for all the talk, there is very little real code. Without being in a training session and with no PHP real examples, learning DDD can be challenging. This book changes all that. It details how to implement tactical DDD patterns and gives full examples of topics such as integrating Bounded Contexts with REST, and DDD messaging strategies. In this book, the authors show you, with tons of details and examples, how to properly design Entities, Value Objects, Services, Domain Events, Aggregates, Factories, Repositories, Services, and Application Services with PHP. They show how to apply Hexagonal Architecture within your application whether you use an open source framework or your own.

General Overview


As explained in the chapter 1Getting Started with Domain-Driven Design, our Domain is organized internally into Subdomains. Each Subdomain is ideally modeled and implemented by one Bounded Context, but sometimes more than one is needed. If well designed, each Bounded Context is an independent system that will be developed and managed by a team. Our suggestion is to implement each Bounded Context with a whole Application. This means that two Bounded Contexts won't live in the same code Repository. As such, they can be deployed independently, have a different development cycle, or even be developed using different languages. Inside your Bounded Contexts, you'll use modules to group Domain objects that hold a strong relation to one another.
