Undefined variable: DOCUMENT_ROOT

[cutecode]

I'm trying to execute a samle PHP program.
But whenever I open a page it gives me errors/warnings
like this:

Warning: Undefined variable: DOCUMENT_ROOT in C:\InetPub\wwwroot\chat\chat\config\config.lib.php on line 2

Fatal error: Failed opening required '/design/db.php' (include_path='') in C:\InetPub\wwwroot\chat\chat\config\config.lib.php on line 2 

this "line 2" looks like this:

require($DOCUMENT_ROOT."/design/db.php"); 

If I write in a .php page this line

$DOCUMENT_ROOT = "C:\InetPub\wwwroot"; 

then everything works fine.

I was told that $DOCUMENT_ROOT works only in xNUX,
and that I should write the above line in every page.

Is it true ?

then everything works fine.

I was told that $DOCUMENT_ROOT works only in xNIX,
and that I should write the above line in every page.

Is it true ?

You've just posted the same thing three times.

According to http://lists.omnipotent.net/php3/199806/msg00123.html , the Web server sets the DOCUMENT_ROOT value, and it doesn't have anything to do with PHP.

This appears to be a list of IIS/PWS server variables:

So, most likely, IIS does not set that var.

And if you're in a function, make sure that you pulled the ol' global $DOCUMENT_ROOT on it.
