Can you discuss the event loop concept and its relevance to asynchronous PHP (e.g., with ReactPHP, Swoole)?
Article Introduction：Yes, event loops are very important in modern PHP development, especially when building real-time or high-concurrency systems. Event loops are the core mechanism of asynchronous programming, allowing PHP to handle multiple tasks without waiting for each operation to complete. ReactPHP and Swoole implement event loops in different ways: ReactPHP adopts a Node.js-style callback model, suitable for small asynchronous tools; Swoole embeds optimized event loops and supports coroutines, which facilitates integration with existing frameworks. Using event loops can improve resource utilization, achieve low latency and real-time functions, but it is necessary to avoid blocking functions, pay attention to shared state risks, and perform load testing.
