            最近在公司利用直播间搭建一个图文直播间时正好要用到chatsever,研究了一下html5的websocket 实现了双向通信,根据前人的经验折腾了几天弄了个聊天室,实现了发送图片,发送QQ表情,群聊私聊等功能,特地分享给各位新手参考学习,大牛可以忽略。

很多童鞋反应用我的源码项目还是报错,不能运行,说下详细安装部署步骤。
首先把下载下来的源代码解压放到web目录下,比如我的就是applications/Xampp/xamppfiles/htdocs/phpb/websocket,

路径
然后使用命令行工具cd进这个目录,运行命令:
php websocket.php
运行效果图:

命令行操作
接着打开Apache服务器,在浏览器访问http://localhost/phpb/websocket/client.html
运行效果图:
