Global variable problem...

[MaxK]

Hi,

I'm running PHP 4.3.10 on Windows XP (IIS) and I'm having problem with the global variable $DOCUMENT_ROOT.

If I for example write:

<?php
echo $DOCUMENT_ROOT;
?>

I get the error: Undefined variable: DOCUMENT_ROOT

Have I forgot to enable something?

Try the super global $SERVER EX:

echo $_SERVER['DOCUMENT_ROOT'];

Been there, done that...

It seems like IIS 5.1 don't support this variable. Is there another way to get this?

According to one of the user notes on the relevant manual page:

You can add $_SERVER["DOCUMENT_ROOT"] to IIS by editing the Environment Variables of your Windows server (was tested on WinXP SP2).

Right click on My Computer >> Properties >> Advanced.
In the System variables click on 'New' and Type in the name field 'DOCUMENT_ROOT' and in the value field the path to your IIS document root folder.

Don't forget to restart your Windows (IIS restart won't load the new settings).

And according to another:

$_SERVER['DOCUMENT_ROOT'] is supported by IIS, although only when running PHP as an ISAPI module.

Thanks for the hint. I will try this tonight...
