Search engine

I made a dealer search engine. The flash search engine makes contact with fetchdealer.php and this document uses dealers.php for the searching data. Now i’d like to make it possible for other the owner of the website to add dealers to this document. Is it possible or do i need a database? And if i need a database how do i do that? I’m a sort of newbie:hugegrin:

I think it’s possible with another php file with a form to add data. Mayby via XML? So the search engine searches from the XML file instead of the PHP file.
Is there someone who can help me out with it??
