PHP gurus...how are they doing this?

Hi, Am totally puzzled as to how they are doing this. The site is at http://www.teeniesxxx.com/madtgp/submit.php (please note its an adult site so you might not want to go there, also note I am in NO way connected with that site...AT ALL) once a person submits a site, they are doing 2 things that totally puzzle me, 1.showing the number of "outgoing links" 2. counting the number of linked to pictures (eg: href='blah.jpg') and movies (eg: href='blah,mpg') and also giving the size of each movie (this i figured out) and the resulation!! I would like to do the same thing for a cartoon site, can anybody tell me where to begin or some sample code?
