一、效果图

php入门到就业线上直播课：进入学习

二、目录结构

images : 存放图片
js ： js文件
swoole

|----action.php     数据库操作类
|----config.php     数据库配置文件
|----websocket.php     swoole创建websocket协议文件

index.php : 聊天首页
login.html : 登录页面
webqq.sql : SQL数据库文件

三、数据库结构

四、代码部分
4.1、config.php 数据库配置文件

<?php
$database = array(
    'host'=>'127.0.0.1',
