Deep Dive into the Laravel Request Cycle
summary
Explains Laravel’s HTTP request lifecycle in concrete terms: the app boots from public/index.php, Composer autoloads classes, bootstrap builds the Application and registers three core service providers and aliases, and the HTTP Kernel handles requests using Symfony Request/Response objects. Describes routing matching URL/method/host to a Route, controllers receiving full dependency injection, middleware executing via a Pipeline, responses being prepared and echoed, and Laravel reserving a 10k buffer for fatal errors plus running terminate hooks after sending the response.
