本篇文章主要介绍了php+websoket搭建chatserver示例（附源码）的资料,这里整理了详细的代码,有需要的小伙伴可以参考下。
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,
DirCMS内容管理系统6.0
下载
DirCMS内容管理系统，是国内自主研发的一款功能强大而又不失小巧简洁的由PHP+Mysql架构的内容管理系统。DirCMS代码全部开源，便于使用者二次开发或定制；并采用简洁的模板标签技术，使制作模板更加容易，一般情况下，用DirCMS架构一个企业站只需半天时间即可，真正实现功能的简洁，实用，强大，灵活。可广泛应用于架构各类门户站，下载站，企业站，工作室等站点。
路径
然后使用命令行工具cd进这个目录，运行命令：
php websocket.php
