PHPMaster.com:
Handling Collections of Aggregate Roots - the Repository Pattern
May 17, 2012 @ 08:44:37

On PHPMaster.com today they have a new tutorial focusing on using the Repository (a part of the domain driven design architecture) to enhance your model's current functionality.

Unlike mappers, though, which are part of the infrastructure, a repository characterizes itself as speaking the model's language, as it's intimately bound to it. And because of its implicit dependency on the mappers, it preserves the persistence ignorance as well, therefore providing a higher level of data abstraction, much closer to the domain objects.

Included in the tutorial is the full code you'll need to create a simple UserInterface class and a User model that extends it. He also makes a UserCollection class to handle working with multiple User objects and a UserMapper to handle the actual data source fetching. Finally, he implements the Repository on top of this base structure showing how it lays on top of everything via the UserMapperInterface instance. At the end some example code showing it in use is also included - making the PDO connection, creating the UserRepository and fetching by a few different data types (email, name and role).
