Server variable $_SERVER["DOCUMENT_R OOT"]

[sakthipro]

Hi,
I am using the Linux Server and server variable $_SERVER["DOCUMENT_R OOT"] to get the root folder to open a text file located in the folder for ex.

fopen($_SERVER["DOCUMENT_R OOT"]."/folder/file.txt","r");
......


I want to use the same scripts to work with Windows Server, Is there any way to get the root folder of the domain installation in Windows?
like it should return c:\www


Could any one suggest me?

Thanks in advance

Heya, Sakthi.

$_SERVER['DOCUMENT_ROOT'] evaluates to the path to your server's document root regardless of operating system....

Heya,
I didn't find the variable $_SERVER["DOCUMENT_R OOT"] in the phpinfo() in the Windows server. How to enable this variable in Windows Server?

Heya, Sakthi.

... except for Windows, it seems, which likes to make life difficult.

Do you have $_SERVER['ORIG_PATH_TRAN SLATED'] by any chance?

Alternatively, if you have a file at the document root, you can use dirname(__FILE_ _).

Hi,
Its working in Windows, but is not the situation,
I want a single variable that returns the document root in both servers,
here the _SERVER["ORIG_PATH_TRAN SLATED"] variable is not available in my Linux Server.

For ex,
1. In Linux Server it should refer /www/project
2. Where as in Windows Server it should return D:\www\project

where project is the root for the particular project

Suggest me

Heya,
Actually the problem with dirname(__FILE_ _) is,
When I call this from the root, ie. from /www/projects it solves the situation.

The problem is, when I call from the sub directory inside the root ie.

From /www/projects/aaa, I want to refer the path /www/projects/bbb, here the function returns /www/projects/aaa as result, so the final result will be,

dirname(__FILE_ _)."/bbb" = /www/projects/aaa/bbb which is wrong

Suggest me

Heya, Sakthi.

Try creating a common include file in your document root:

<?php
    if( empty($_SERVER['DOCUMENT_ROOT']) )
    {
        $_SERVER['DOCUMENT_ROOT'] = dirname(__FILE__);
    }
?>
 

Then simply include() this file at the top of any script that needs to use $_SERVER['DOCUMENT_ROOT'].
