主要的函数是start()函数，当中写了注释内容，可以根据自己的需要进行修改
3、客户端JavaScript websocket
websocket 发送``` 这里客户端页面加载后就与服务器端进行毗连，如果成功之后，就会实行onopen，如果服务器发送内容，实行onmessage，此中event是服务器发送的对象。查看更多
4、运行步骤
1）下载源代码至本地
2）修改run.bat文件存放路径
3）双击运行脚本
4）打开浏览器，我是放在Apache的www文件夹下面的，输入http://127.0.0.1/websocket/wobsocket.html
5）如果报错
https://img-blog.csdn.net/20170614163834910?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQveHVqaW5nMTk5MjA4MTQ=/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/SouthEast
表示Server_socket.php 没有实行，也大概是火狐浏览器的websocket没有打开。
打开火狐浏览器的websocket方法
1）地址栏输入about:config
2）回车，搜索框输入websocket，将与websocket有关的内容全部打开，重启浏览器。

6）实行效果
https://img-blog.csdn.net/20170614164146208?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQveHVqaW5nMTk5MjA4MTQ=/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/SouthEast
左边的cmd是实行run.bat的脚本
右边的控制台是客户端实行的有关打印
可以看出，客户端发送的信息被服务端接收，并且服务端发送的内容客户端也可以被接收。
之以是要做这个是有关实现团队前端主机创建成员，从机参加后，推送消息给主机，是哪一个成员参加，以及主机点击开始操作之后，主机和从机同时进入操作页面。
另外，还大概后期还会有操作期间的会话，其实这个已经可以简单实现，不外题目是需要区分团队，每一个团队有一个聊天室。以及发送消息区分每一个用户。大概后期会参考打开，以及打开
