In this tutorial, I'll show you how to combine RSS, Ajax, and JavaScript to create a live RSS ticker. Thanks to Ajax, the conventional roles of server side and client side programming are reversed in an application like this as JavaScript- not PHP- is used to handle much of the work, including parsing the RSS file.
A quick overview of how our Ajax RSS ticker works:
A very simple PHP script is used to get the contents of an RSS file online and save it locally on the server for caching, unparsed in any way.
Ajax is used to fetch the contents of the RSS file produced by the PHP script.
JavaScript receives the contents of this RSS file (via Ajax), then parses it using standard DOM methods before displaying the feed in any manner the webmaster desires.
