Explain the lifecycle of a controller in FuelPHP.

Answer: In FuelPHP, the lifecycle of a controller involves the following steps:

1. Routing: When a request is made, it is routed to a specific controller based on the URI.

2. Controller Initialization: The framework instantiates the controller class defined in the routing configuration.

3. Before Method: Before the main action method is executed, the `before()` method (if defined) is called. This method is often used for setup tasks, such as authentication or loading common resources.

4. Action Method: The appropriate action method (e.g., `action_index`, `action_create`) is invoked. This method handles the core logic of the request, such as processing data, interacting with models, and preparing the response.

5. After Method: After the action method execution, the `after()` method (if defined) is called. This method can be used to perform tasks like logging or modifying the response.

6. Response Generation: The data prepared in the action method is transformed into a response, which may include rendering a view or returning JSON.

7. Output: Finally, the response is sent back to the client, completing the request-response cycle.

This lifecycle ensures clear separation of concerns and structured handling of web requests within a FuelPHP application.
