This article example for everyone to share swoole create multi-person multi-room chat room specific code, for your reference, the specific content is as follows
Core swoole code
The basic cs (client-sercer) structure remains unchanged, and the hash of redis and set are used here to store and group; So as to achieve the functions of grouping, statistics, timing push and the like; Finally, the onclose event is used to eliminate the disconnected connection. The whole code is as follows: (If you don't do the front end, you won't show it.)
