Do you mean you want to add RSS feeds from other sites or create a feed for other sites to read in?

If it's the former then have a look at SimplePie - SimplePie: Super-fast, easy-to-use, RSS and Atom feed parsing in PHP.. I use it on this site - The UK Motorsport Calendar of Events. Here's a page example - Formula 1 News

This is a great way to create dynamic content without any ongoing effort.

Thanks for help me and give me the link

It sounds like you want to display an RSS feed within your HTML website. The easiest/best way to do this is to use RSS2HTML a free PHP script. This means that you can retain the complete control of the HTML layout (using templates) and make it match your existing design. Additionally using PHP rather than JavaScript will mean that search engine spiders can "spider" the contents of the RSS feeds.

Additional details and a free rss2html download is available at: RSS2HTML free PHP script for displaying RSS feeds
Additional information and other options for displaying RSS feeds can be found at: Displaying RSS Feeds
Goodluck!
