[fmx2004] passing variables from html to flash

After reading a few posts, I wasn’t able to find the answer to this.

I want to have links on several pages of my website which, when clicked, take the user to an html page called “portfolio.htm” which has a flash portfolio on it. This portfolio is set up with a series of buttons which load external .swf files for each project. How do I tell flash which .swf to load when the flash file opens.

ex: user clicks on “project x” on a web page called print.htm. The user should then be taken to portfolio.htm where a flash file resides and loads “project x” into a movie clip called “content_mc”.

All the other posts I’ve read make reference to PHP. Is it neccesary to use PHP, or can I achieve this without PHP? Thanks for any advice you can offer.
