How to create a RSS News Ticker

Hey everyone,

 I'm trying to create a RSS news ticker. I have found a ticker I like which is 
free and easy to implement but am not sure how to get the RSS to feed into it. 
This is the website I found the ticker on:

 http://www.mioplanet.com/rsc/newsticker_javascript.htm

 It says "if you want to import data using PHP to convert it into a single
HTML 
line to be displayed by the ticker, create a php script to import and convert 
the data." Does anyone know how to do this or of anyother news tickers
which 
would be better suited?

 Many thanks,

 Sean
