How do you handle the variables specific to the environment you use: Development, QA, Production, etc? Environmental Variables of course. But WHAT are they, WHY should you use them, WHERE do you put them, and HOW are they used. As an added bonus, Environmental Variables are not limited to PHP!

I thought this was excellent. It was light-hearted and fun. I can always appreciate someone willing to do live demos at a talk. That's real world excellence right there. Maybe add a little more about security concerns and how to address them since I would guess most people use environmental variables for things like keys, auth codes, etc...
