Create RSS Feed in php

First of all I want to discuss about the best use of RSS Feed. Most important feature is that RSS is a part of XML and it is cross language i.e. we can use it in any language. Suppose we generate a RSS in php , It can be use in JAVA, ASP, .net, ROR etc . It is better replacement of database connection also. We can display updated data without using database connection. RSS will work for that..

Well here is script in php which generate RSS feed from database .
