Laravel Request Lifecycle

The Laravel request lifecycle refers to the series of events that take place when a request is made to a Laravel application. Here are the key steps involved:

1. The request is first received by the web server, which passes it on to the Laravel framework.
2. The framework then boots up and initializes various components, such as the service container and service providers.
3. The router component examines the request and determines which route to use based on the URL and HTTP method.
4. The middleware stack is then executed, which can perform various tasks such as verifying authentication, performing input validation, and more.
5. The route handler, which is typically a controller method, is then invoked. The method performs the required business logic and returns a response.
6. The response is passed back through the middleware stack, which can modify it or perform additional tasks.
7. Finally, the response is sent back to the web server, which returns it to the client.

This request lifecycle is fundamental to how Laravel works and understanding it can help in debugging and optimizing Laravel applications.
