In this article we are going 
to discuss how to create 
a PHP-based RSS reader. It would 
be helpful if you know something about
 XML, but not really necessary. 
RSS documents have three main tags: Title, 
Link and Description. And they all do exactly 
what their names suggest. I will go into detail 
about these tags in my second article dealing 
with “building an RSS file.� For now, we 
will only focus on the “reading� part of 
the article.
