  • What is Domain-Driven Design (DDD) and how can its concepts be applied to a PHP project?
    What is Domain-Driven Design (DDD) and how can its concepts be applied to a PHP project?
    The application of DDD in PHP improves code maintainability and business alignment by focusing on business domain modeling. 1. Organize code using a domain-centric directory structure; 2. Correctly implement entities with unique identification and attribute-based value objects; 3. Maintain data consistency through aggregation roots; 4. Define warehouse interface isolation and persistence logic; 5. Decouple business operations with domain events; 6. Divide boundaries in large projects and clarify boundaries; finally, unified development and business communication with common languages, so that the code clearly expresses business rules, which are suitable for complex business scenarios, and gradually introduces software architectures that can avoid over-design, thereby realizing high cohesion and low coupling.
