Free PHP Web Server for Dreamweaver?

I’m trying to learn PHP and have Dreamweaver. Does anyone know where I can get my little hands on a free testing server I can run locally on my machine so I can see if my code works.

And if it’s not too much trouble, how I go about setting it up with Dreamweaver. I really haven’t a clue and Google hates me…

Any other advice would be appreciated as well.
