Un common question to maybe a simple solution. Your help please!

Good Morning to All! I have a question that I am sure someone could answer or guide me to the right path.

I am learning how to work with databses PHP/MYSQL to be exact. I wanted to build a flash template that would be called from the database when a user clicks on a link.

so far that is easy. What I want to do is have different content in this case FLV’s load in the template based on who clicked on the link. So if the users are A B and C I want something different to play when A, B or C clicks the link.

Anybody have any ideas where I could start? Any tutes similar to what I am trying to do.

Thanks a lot for any help given.
