PHP客服聊天
1、基于workman框架
github:https://github.com/walkor/workerman-chat
文档：http://www.workerman.net/gatewaydoc/
demo:
2、前端代码
var client_name,user_id,client_name;

// 当socket连接打开时，输入用户名
ws.onopen = function (ev) {

console.log("websocket握手成功，发送登录数据:"+login_data);
ws.send(login_data);
};
// 当有消息时根据消息类型显示不同信息
ws.onmessage = function (e) {
console.log("onmessage "+e.data);
var data = eval("("+e.data+")");
switch(data['type']){
// 服务端ping客户端
case 'ping':
ws.send('{"type":"pong"}');
break;;
// 登录 更新用户列表
case 'login':
if(data['client_list']){
client_list = data['client_list'];
flush_client_list();
bindEvent(username,uid);
localStorage.setItem("kefu_name"+getDates(),data['client_name']);

4、启动PHP服务文件
php event.php start
