What does swoole do?

Swoole is an asynchronous multi-threaded server written in C language and supports PHP language. Its functions include asynchronous TCP/UDP network client, asynchronous MySQL, asynchronous Redis, and database connection pool , AsyncTask, message queue, millisecond timer, asynchronous file reading and writing, asynchronous DNS query, etc.

swoole can mainly be used to solve long-time-consuming tasks. There is no concept of process or thread in PHP. However, swoole can be used as an extension of PHP to use processes and threads, and can be used to solve concurrency problems.

Secondly, there is a Websocket service in the swoole framework, which can be used to implement online IM systems and chat room functions;

can also be used to solve some scenarios that require timing functions.

What swoole can do

1. Used to send emails, broadcasts, and scheduled tasks; swoole supports asynchronous task functions, so it can be used to do some emails, Broadcast push function; secondly, it has a millisecond timer, which can be combined with the asynchronous task function to send scheduled tasks, imitating the crontab task in Linux;

2. The transmission function of positioning function; such as delivery when ordering takeout The mobile position of the map during the delivery process can be used to obtain the information of the delivery person asynchronously in real time;

3. Development of IM system and chat room function; swoole has Websocket server function. After the front end sends information to the client, The server can accurately push messages to the other end, thereby achieving real-time communication.

4. System monitoring function; it can asynchronously record the data requested by HTTP and monitor each request of the system;
