I do a websocket demo (PHP server), Websocketdemo

Notice

Execute PHP files from the command line such as Php-q c:\path\server.php

Access http://127.0.0.1/websocket/index.php from a local Web server

Notice
Requires php5.3 or more of the execution environment, and a Web server such as Apache
Browsers need to support HTML5 Web sockets
This listens to socket port 9505, which may need to modify the port within these two files or kill the corresponding port process if the port is encountered

The page looks better on the phone than on the PC!
