创建类websocket($config); 
$config结构: 
$config=array( 
  'address'=>'192.168.0.200',//绑定地址 
  'port'=>'8000',//绑定端口 
  'event'=>'WSevent',//回调函数的函数名 
  'log'=>true,//命令行显示记录 
); 
  
回调函数返回数据格式 
function WSevent($type,$event) 
  
$type字符串 事件类型有以下三种 
in  客户端进入 
out 客户端断开 
msg 客户端消息到达 
均为小写 
  
$event 数组 
$event['k']内置用户列表的userid; 
$event['sign']客户标示 
$event['msg']收到的消息 $type='msg'时才有该信息 
  
方法: 
run()运行 
search(标示)遍历取得该标示的id 
close(标示)断开连接 
write(标示,信息)推送信息 
idwrite(id,信息)推送信息 
  
属性: 
$users 客户列表 
结构: 
$users=array( 
[用户id]=>array('socket'=>[标示],'hand'=[是否握手-布尔值]), 
[用户id]=>arr..... 
)
