Hi,
Sorry if this is a dumb question. Is there a way in php to get the
physical path the document root of my website? I want to open a file in
the root of my web server, i.e. "/", but I won't always know what the
physical path to the web root is, and it will vary depending on the
machine the web app is running on. I've tried using "realpath" (e.g.
realpath("/")) but it doesn't really work. Thanks.
