Laravel MVC: quickstart guide
Laravel was chosen for its elegant syntax, powerful features and MVC architecture. 1) The MVC mode separates data (model), logical flow (controller) and presentation (view), improving the maintainability and scalability of the code. 2) Shows how the model, controller and view work together through code examples. 3) It is recommended to keep the model strong, the controller is concise, and the view focuses on display. 4) Laravel's routing system is flexible and can be mapped directly to the controller. 5) Use preload to optimize query performance to avoid N 1 query problems. 6) Follow the DRY principle, reuse code using Blade templates and EloquentORM to maintain consistency and simplicity.
