Hi, I have a list of articles coming from various sources subscribed with my rss feed. But when users click the link, they leave my site to the orignal site providing the articles. How can I keep those articles displayed in detail (provided that the source is acknowledged) in my website without my visitors leaving to others?

do you subscribe to the full article by rss, or just a summary?

if you have the full article in the rss form, just tweak your rss parse to show all of it.

If you just get a summary, you do still have some options

1 - use a target='_BLANK' attribute in the links, that way they open in a new window - your site remains open in the back ground

2 - write some scraping software. the php function file_get_contents('url') will get all the source code form the given url (providing the url fopen wrappers are enabled) - you then need to work out which bit is the article from the source of each page
