This article explores the design and implementation of PHP Hyperf, a high-performance PHP microservice framework. Built on top of Swoole’s coroutine features, PHP Hyperf utilizes asynchronous non-blocking IO to significantly improve concurrency handling, making it ideal for high-load and high-concurrency microservice architectures. The article delves into Hyperf's design philosophy, framework implementation, core features, and real-world application cases, helping developers understand and apply this framework effectively.
