Adding PHP code into my website

[speakeasy602]

I use FP2003 and I have several forms and user comment scripts written in
PHP. Before I do something stupid and just paste the code into my HTML, I
want to know, what is the easiest way to add these to my site?

I'm just not sure how to create the PHP file, other programs allowed me to
create a page that was already set up for PHP.

I used to use dreamweaver 6.0, but it was a totally inconsistant peice of
crap. Now that I've started using FP, I'm a happy camper. I should have used
it since the beginning. So easy... minus the PHP thing.

Thanks in advance!
