The Symfony HttpKernel component provides a structured, event-driven process for converting an HTTP Request into a Response. It is the core engine behind the Symfony full-stack framework and is used by projects like Drupal, Laravel, and Shopware.

Use cases

• build a custom PHP framework or micro-framework
• handle the request-response lifecycle in a PHP application
• add event-driven middleware to HTTP request processing
• create a CMS or application on top of a kernel architecture
• handle exceptions and terminate events during request handling
• process sub-requests in a PHP web application

When to choose

• you are building a PHP framework, CMS, or application that needs a robust request-response pipeline
• you want event-driven extensibility via kernel events (request, controller, view, response, exception, terminate)
• you are already in the Symfony ecosystem and need its kernel internals

When to avoid

• you need a complete ready-made framework with routing, templating, and ORM out of the box - use full Symfony instead
• you are not working in PHP
• you want a micro-framework with minimal abstractions - consider Slim or similar
