What are some use cases for PHP Swoole?

PHP Swoole is a high-performance PHP extension that can be used to develop high-performance, highly concurrent network applications. Its use cases include:

1. Web server: Swoole can directly replace traditional PHP-FPM/Apache/Nginx as a web server, offering better performance and lower resource consumption.
2. Swoole can be used to build high-performance API servers that can handle a large number of concurrent requests.
3. Real-time communication: Swoole supports TCP/UDP/UnixSocket protocols, and can be used to build real-time communication applications such as chat rooms, game servers, etc.
4. Swoole can be used to create high-performance proxy servers to achieve functions like load balancing and reverse proxy.
5. High-performance web crawler: Swoole offers features such as asynchronous programming and coroutines, which can be utilized to construct high-performance web crawlers, improving the efficiency of data collection.
6. High-performance message queue system: Swoole can be used to build a high-performance message queue system, enabling functions such as asynchronous task processing and event-driven architecture.

In general, Swoole is primarily suitable for scenarios where there is a high demand for performance, requiring the processing of a large number of concurrent requests, and can significantly improve PHP program performance and concurrency capabilities.
