What is Request lifecycle in Laravel, and what role does it play in a real application? In Laravel, request lifecycle should be understood as part of a larger application architecture rather than as an isolated API call. A web request enters Laravel through the application entry point, passes through bootstrap and middleware layers, reaches routing and application logic, and eventually produces a response. A strong understanding includes its purpose, the layer where it belongs, the data or request flow it affects, and the situations where another mechanism may be more appropriate. Practical context: Laravel is a PHP application framework that provides structured tools for routing, controllers, database access, validation, authentication, queues, caching, filesystem operations and testing. The specific focus here is request lifecycle: A web request enters Laravel through the application entry point, passes through bootstrap and middleware layers, reaches routing and application logic, and eventually produces a response. This question is designed to test not only terminology, but also how the concept fits into Laravel's request, application, database, security, or deployment workflow.
