Hyperf is an extremely performant and flexible PHP CLI framework based on Swoole 4.5+, powered by the state-of-the-art coroutine server and a large number of battle-tested components. Aside from the decisive benchmark outmatching against PHP-FPM frameworks, Hyperf also distinct itself by its focus on flexibility and composability. Hyperf ships with an AOP-enabling dependency injector to ensure components and classes are pluggable and meta programmable.
