root path to directory Help please

[classifieds100]

Hi,

I have a script in which I need to get these two values automatically:

full root path to directory (ie: /www/data/docs/user.com/public)

$this->directory_root = ".";

http path to directory (ie: http://user.com/public) (no trailing slash)

Note: this must be a directory path you cannot use http://user.com/public/sitemap.php

$this->homepage = ".";

I have try to replace the first $this->directory_root = "."; with:
$this->directory_root = "$_SERVER['DOCUMENT_ROOT'] . dirname(FILE)";

But I'm sure I get it wrong somehow.

And the second part I also can't get it to work either.

See more here:

############################## CONFIGURATIONS #################################

html page on/off toggle writing of html header and footer

$this->html = "on";

width of <table>

$this->table_width = "100%";

on/off

$this->debug = "off"; / turn off/on display of working path. not recommened to leave
on during public use. /

full root path to directory (ie: /www/data/docs/user.com/public)

$this->directory_root = ".";

http path to directory (ie: http://user.com/public) (no trailing slash)

Note: this must be a directory path you cannot use http://user.com/public/sitemap.php

$this->homepage = ".";

http path to images

$this->img_src = "/images";

alternating row color;

$this->alt_color = "on"; / on/off /
$this->alt_color_one = "#f6f6f6";
$this->alt_color_two = "#c0c0c0";

show directories first on/off

$this->order = "on";

blacklist file names and directories so they will not show

$this->blacklist = Array(".",
"..",

.... rest of the code goes here....

Please can someone help me to get right these values

$this->directory_root = ".";
$this->homepage = ".";

automatically from the server?
