好思路！
其实不仅php可用，任何服务器技术均可！

Using the XMLHttpRequest Object Now that we’ve discussed the history of dynamic Web applications and introduced Ajax, it’s time to cover the heart of the matter: how to use the XMLHttpRequest object. While Ajax is more of a technique than a technology, without widespread support for XMLHttpRequest, Google Suggest and Ta-da List wouldn’t exist as we currently know them. And you wouldn’t be reading this book!

AJAX driven simple chat
Detailed description:
This class can be used to implement a simple Web based chat system that uses AJAX to update the chat dialog display area without reloading the whole page.
这类可以用来实现基于聊天系统的简单网络。此聊天系统使用AJAX更新闲谈对话显示区而无需重新调入页面
The class generates a page with a Web form to submit what each chat line that the users type.
这类产生 Web form形式的网页
The chat lines are sent to the server using a XMLHttpRequest object.
使用XMLHttpRequest对象将chat lines发到服务器
The chat lines are received by a server side script that uses the class to store what each user entered in a MySQL database table.
服务器端接受了chat lines，并用它来储存用户送进MySQL数据库表的数据。
In response, the class outputs the chat list already formatted to by displayed in the user browser pages.
相应地，在用户浏览网页时，它输出已经被格式化显示的的聊天列表。

AJAX is a promising and rapidly evolving approach for building highly interactive web applications. In AJAX, user interface components and the event-based interaction between them form the founding elements, whereas in classic web applications the notions of web pages and hypertext links are central. Therefore modelling AJAX requires a different approach than what the current web modelling tools are providing. In this paper we propose a UML scheme for modelling AJAX user interfaces based on the MDA approach. We adopt ANDROMDA for creating an AJAX cartridge to generate an entire AJAX-based web application with automatic back-end integration. The implementation of this cartridge is a work in progress.

这是一个关于Ajax很好的英文文档，可供有一定经验的程序员参考
