[PHP] How can I stop PHP from resolving symlinks?

[Roy Souther]

I am trying to stop PHP from resolving symlinks. I have a PHP CMS that I use to host dozens of sites using Apache virtual hosting features. I need all the sites to run the exact same PHP CMS code but use their unique directories to host the different config files. The problem is that the PHP scripts are running from the directory that the links point to and not the directory where the site is. The big problem with that is the CMS tries to read a configuration file that is in a relative location to the PHP script like ../config.php. 

[EMAIL PROTECTED] ls -l /usr/local/cms
-rw-r--r--  1 user users     20     Jan 16 02:17 index.php
drwxr-xr-x  9 user users     4096   Feb 22 16:40 admin
[EMAIL PROTECTED] ls -l /vhost/test01.com/var/www/html/
-rw-r--r--  1 user users     20     Jan 16 02:17 config.php
lrwxrwxrwx  1 root root      31     Feb 22 14:05 index.php -> /usr/local/cms/index.php
lrwxrwxrwx  1 root root      31     Feb 22 14:05 admin -> /usr/local/cms/admin
[EMAIL PROTECTED] cd /vhost/test01.com/var/www/html/admin/
[EMAIL PROTECTED] pwd
/vhost/test01.com/var/www/html/admin
[EMAIL PROTECTED][admin]#

Bash is doing what I need. It sees the current directory as the full path of the symlink.

The admin.php at this point only has system("pwd"); in it and it prints out /usr/local/cms/admin as the directory it is in, not what I want. It will never see the ../config.php file.

I tried doing this 
chdir ($_SERVER[DOCUMENT_ROOT]."/".$_SERVER[REQUEST_URI]);
but it still resolves the link and does not accept the path that I constructed.

How can I make PHP use the symlink and stop trying to resolve the original files?
