how do I return to a different directory in PHP

[Mathanan]

I am writing a script that uses different directories to get php files and html files.

directory structure looks like this

/includes (directory to php files)
/secure (directory to HTML files)
/ (root directory to index.php)

I have been looking at the $_SYSTEM['DOCUMENT_ROOT'] and trying to get it to return the / directory, but it ends up going to the httpd/PRIMARY directory which is not in the same website that I am working on. I am lost. .. lol

this is the code I have been trying. . .that does not work.

$level_page = ($_SERVER['DOCUMENT_ROOT']."/secure/level1.html");

Oh, I am using SME 7.4 server and PHP 4.3

Try the dot-slash directory prefix (./). That resolves to the root directory execution started in.

what syntax would I use to put that in?

chdir("./") ?
