Does the swoole coroutine belong to a process or a thread?
The swoole coroutine belongs to threads. Coroutines are executed in threads. Coroutines are lightweight threads. The underlying implementation of Swoole's coroutines is single-threaded.

What is the usage of semaphore in swoole
In swoole, semaphores are mainly used to protect shared resources so that there is only one process at a time; when the value of the semaphore is positive, it means that the thread under test can be locked for use. If the value of the semaphore is 0, then It means that the thread under test will enter the sleep queue and wait to be awakened.

What is the implementation principle of swoole coroutine?
In swoole, the Swoole server receives data and triggers the onReceive callback in the worker process to generate a coroutine. Swoole creates a corresponding coroutine for each request. Sub-coroutines can also be created in the coroutine. The underlying implementation of the coroutine is single-threaded. Therefore, only one coroutine is working at the same time.
