Username Based Directory
I am making a registration form and I would like to have the php script that parses the form to create a directory based on the username a visitor chooses.
So.. if a vistor chooses "johndoe" as a username, I would like the php script to create a directory called "johndoe" under a pre-existing directory called "users".
I know this must be really easy to do, but I can't find out how to do it in the "Beginning Apache, PHP, Mysql" book I got from you guys.
Thanks for your help!
