How to get the document root (public html folder)?

Hello, I am running PHP 4 on my Fedora Core 2 dev machine, Apache
1.31. I made a
lot of calls to $_SERVER['DOCUMENT_ROOT']. Unfortunately, when I move
my application to a Windows environment, running on an IIS web server,
the variable $_SERVER['DOCUMENT_ROOT'] is no longer supported (I
always get an empty string).

Question: What is a cross-web server way of finding the path to the
document root -- the path to the public html folder?

Thanks for your help, - Dave

For most scripts you could try to obtain your current working directory and
remove the path given in REQUEST_URI (or maybe another one, that fits
better).

var_dump($_SERVER) should help you.

You must have something wrong with your server setup because I am running
PHP on Windows XP and all the $_SERVER variables are there. However, I am
running Apache, not IIS, so the fault must be with IIS. What shows up when
you run phpinfo()?

I believe you need to have PHP as Apache module to get the DOCUMENT_ROOT
variable. Otherwise, PHP has no way to know such details from virtual
hosts.

basedir() and $_SERVER['PHP_SELF'] can be a good start.
