all you need to do to destroy a session is call

session_destroy();

you don't need to unset variables before then.

session_unregister is depreciated anyway.

if you want to remove something like the uname part of the session array just use

unset($_SESSION['uname']);

I've always just done

function destroy_sess($sessname = "all sessions")
{
	if($sessname == "all sessions")
	{
		$_SESSION = array();
	}
	else
	{
		$_SESSION[$sessname] = NULL;
		unset($_SESSION[$sessname]);
	}
}

and that works fine for everything that I do.

BTW: session_unregister() is not forward compatible with php6
