I have a question....

Webmaster, I'm in the situation where at my place of employment, they do not have PHP support on our web server but I'm trying to teach myself at home and when I have spare time at work, I'd really like to be spending it by playing around with PHP. Is there a program out there, kinda like a shell where you can edit the code and then flick over within the same program so it then shows you a preview of what you're working on without have a web server around or installed?
