Re: How can I stop PHP from resolving symlinks?

You need to check your httpd.conf and make sure the "Options FollowSymLinks" 
is set for the server.  Check the apache documentation for further 
information.

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.

root@ttyq0[~]# 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
root@ttyq0[~]# 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
root@ttyq0[~]# cd /vhost/test01.com/var/www/html/admin/
root@ttyq0[admin]# pwd
/vhost/test01.com/var/www/html/admin
root@ttyq0[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?
