Quick Answer
DDD separates business logic into a domain layer with Entities, Value Objects, Aggregates, Repositories, and Domain Services. In PHP: Entities are classes with identity (User with ID), Value Objects are immutable (Money, Email), Aggregates enforce consistency boundaries, Repositories abstract persistence. Doctrine ORM fits well with DDD. Focus on modeling the business domain first, not the database.
Answer
DDD structures software around domain models and uses value objects, aggregates, and repositories. Works well with Symfony and Laravel.
