How can I write PHPsocket code to accept the data sent from the client websocket?

How can I write the PHPsocket code to accept the data sent from the client websocket? how can I write the PHP socket code to accept the data sent from the client websocket?


Baidu hasn't seen the complete code for half a day, and it's not a good tutorial.

We recommend that you directly use workerman, which has a ready-made php websocket server and has excellent performance.
The following is an online demo of the websocket of three workerman workers. The source code and comments on the official website are also detailed. it is worth reading.

I have never used the data sent from the client, and I have to change it myself .. I want to write native

Who can help write a native one.

Ready-made online
