Introduction to FastRoute
FastRoute is a high-performance HTTP request router for PHP. It provides a simple and efficient way to map HTTP requests to your application handlers, making it perfect for building REST APIs and web applications.What is FastRoute?
FastRoute is a routing library created by Nikita Popov that focuses on speed and simplicity. Unlike full-featured frameworks, FastRoute does one thing exceptionally well: routing HTTP requests to their corresponding handlers.FastRoute uses a highly optimized regular expression-based dispatcher that makes routing decisions in microseconds, even with hundreds of routes.
