随着网络的逐渐普及，以及网络技术的不段发展，人们通过网络进行交流的方式变得多样化。网络聊天室便是其中之一。聊天室系统的即时交流方式满足了网络中多人同时聊天交流的需要，使得较多的人在同一个聊天页面进行交流变得方便，简单。

本设计所完成的网络聊天室具有常用聊天室的所有功能，包括多人同时在线聊天、两人间的私密聊天、在发言的时候能够发送表情及图片，还能显示在线用户列表，同时，为了管理聊天室中的用户，设计了用户注册登陆功能，用户管理功能以及用户留言功能。并且，加入了分屏、清屏、屏蔽的辅助功能，增加了聊天室的操作性。

本文首先介绍了聊天室系统所使用到的一些关键技术，接着介绍了该系统的设计思路和需求分析，然后是对系统的详细介绍，包括系统中创建的数据库以及系统的具体功能介绍。
