Another useful variable is $REMOTE_USER which contains the username of a person authenticated through htaccess. One gotcha to watch out for with this one is referencing it in included files. It does not get passed to included files, just the main page, so you have to pass it in to your included files as a set global or as a function parameter. [Editor's Note: $REMOTE_USER is a global variable that is not accessible inside a function definition unless imported using the global keyword. i.e. function foo () { global $REMOTE_USER; //... } --zak@php.net]
