My websocket demo (php server) and websocketdemo

Notice:

Execute the php file through the command line, such as php-q c: \ path \ server. php.

Access http: // 127.0.0.1/websocket/index. php through a local web server.

Notice:
Php5.3 or above is required, and a web server such as apache
The browser must support html5 web socket
Listen to socket port 9505 here. If the port is occupied, you may need to modify the port or kill the corresponding port process in the two files.

The mobile phone on the page looks better than on the pc!

2. php file of socket server code

In the future, I will make a full copy of the java version.
