How to get the Root Path to just above public_html...

[listenmirndt]

I don't know what the server root path is going to be...
but I need to be able to access just above public_html with PHP and create a directory there (for secure file storage).

So - is there anyway i can get that path?

I know I could do $_SERVER[DOCUMENT_ROOT] to get the path to within public_html,

but since this script has to run on different servers, I can't rely on the format of the path to say, explode and create a path out of document_root...

any ideas would be great!

You want the name of the directory that contains [font=monospace]$_SERVER['DOCUMENT_ROOT'][/font]? [man]dirname[/man].
