The Laravel Lumen Framework.
Laravel Lumen is a PHP micro-framework designed for building web applications quickly and efficiently with a focus on expressive and elegant syntax. It aims to simplify common development tasks such as routing, database handling, queueing, and caching. While Lumen has been known for its speed and ease of use, the recommendation now is to start new projects with Laravel due to performance improvements and the availability of Laravel Octane.
Laravel is a powerful and elegant PHP framework that provides developers with a comprehensive set of tools and features to build robust web applications. It follows the Model-View-Controller (MVC) architectural pattern, offering a clean and organized structure for writing efficient and maintainable code.
