一、效果圖

二、目錄結構

images : 存放圖片
js ： js文件
swoole

|----action.php     數據庫操作類
|----config.php     數據庫配置文件
|----websocket.php     swoole創建websocket協議文件

index.php : 聊天首頁
login.html : 登錄頁面
webqq.sql : SQL數據庫文件

三、數據庫結構

四、代碼部分
4.1、config.php 數據庫配置文件

"127.0.0.1",

    "charset"=>"utf8"
);

4.2、action.php數據庫操作類
