How to define the webroot??Help me

I have got this code from PHP tutorial on the website.

$thisFile = str_replace('', '/', __FILE__);
$docRoot = $_SERVER['DOCUMENT_ROOT'];

$webRoot  = str_replace(array($docRoot,
'library/config.php'), '',
$thisFile);
$srvRoot  = str_replace('library/config.php', '',
$thisFile);

define('WEB_ROOT', $webRoot);
define('SRV_ROOT', $srvRoot);

I can't understand the meaning of the line -->$thisFile
=
str_replace('', '/', __FILE__);

I know the function str_replace.

I want to know what should be the file"__FILE__"
here??

Plz describe briefly as I can understand.

Hello,

I think perhaps the script was pasted in here incorrectly? 
The back-
slash should be escaping the single quote, therefore causing
an
error.  Thats my initial thought at least.

Perhaps you'd like to explain the usage of WEB_ROOT and
SRV_ROOT?

You might also want to check out the 'dirname' function in
PHP - you
would be able to use that to easily determine a location of
the
current file...

Hi!,

"__FILE__" is a reserved keyword under PHP and
returns the filename of
the script that is currently being run.

Hope this will help you.

Ojasvi.
