我做的一个websocket的demo(php server)，websocketdemonotice:
通过命令行执行php文件  如 php -q c:\path\server.php
通过本地web服务器访问 http://127.0.0.1/websocket/index.php即可
notice:
需要php5.3或以上的执行环境,和一个web服务器如apache
浏览器需支持html5 web socket
这里监听 socket端口 9505,如遇到端口被占用可能需要在这两个文件内修改端口或者杀死相应端口进程
页面手机上看起来比pc上好看!
1.客户端代码 html文件
1.client code: chatdemo class=container> class=title>简易聊天demo
class=content> class=show-area>
class=write-area> class=btn btn-default send >发送

2.socket服务器端代码 php文件
