Describe the architecture of a Symfony application.

Answer: The architecture of a Symfony application is based on the Model-View-Controller (MVC) pattern. It consists of the following key components:

1. Bundles: Modular components that encapsulate features and can be reused across applications.
2. Controller: Handles incoming requests, processes user input, and returns responses.
3. Models: Represents the data and business logic, typically interacting with the database using Doctrine ORM.
4. Views: Templates that render the user interface, usually using Twig for templating.
5. Routing: Defines URL patterns that map to specific controllers and actions.
6. Services: Reusable classes managed by Symfony’s service container, promoting dependency injection.
7. Configuration: Central management of application settings, typically defined in YAML or XML.

This architecture promotes separation of concerns, making applications easier to maintain and scale.
