How's it going?

Just a quick question, I hope!:

I'm running my setup locally, and could do with creating a directory in windows from a script (e.g. a directory called test on my C:drive).

If I was running on a Unix or Linux system, I could probably use MkDir, but for windows, how do I do this please? Is there a DOS command shell or something in php?

Thank you, if you can help.....
