PHP & html local testing

I was looking at creating an html form and then passing its variables into a php file for formatting and other things like that. This works when I load my php file and my html form onto a remote server but I can not figure out how to test this form and php file locally. I was wondering if someone could create a simple form and then a simple php file and tell me how I can test that combination locally? I was trying to just create a form that allows a user to enter two numbers into two seperate fields and then hit submit and have the numbers added together and have the sum displayed. Also, are there any chat rooms dealing with php or does anyone around here use icq? Thanks, if you want to reply personally remove all numbers from my address. -- Andrew V.
