Subdomain - fetch files from main domain except config

Hi.
I'm currently trying to set up a WAMP-install with subdomains which will fetch the files from the main domain, except for the config-file, which will differ among the subdomains.

Something like:
www.example.com -> loads fine, everything works, default config
test.example.com -> loads the same files as above, except it loads its own config

I've got the subdomain working (except I had to remove my .htaccess from the main domain, but I'll get around to fixing that later), but I'm wondering if I can do anything to make everything work on the Apache side, or if I need to fix the code running on the main domain to cater for subdomains.

Any suggestions would be appreciated

 

Which "config" you wish to be differ? .htaccess ?

 

No. The site has a config.php which will be different for each user (different credentials, different DB etc) - so it would be simpler to just have a main set of files, and then subdomains / subfolders for each separate entity using the system. While I understand that I need to modify some of the code to allow for the files to work as intended, I was just wondering if there was a way to let Apache believe that the files should be served from the main root folder, instead of the current subdomain.

 

You may include different configs like this

/*

   Configs directory structure
   ---------------------------

   /configs/config.php   - default config
   /configs/webmail/config.php - config for "webmail" subdomain
   ...

*/

$legitSubdomains = array('webmail','store','blog','developer');
$configsRootPath = '/configs/';

if(preg_match('#^(?:([^\.]+)\.)?yourdomain\.com$#', $_SERVER['HTTP_HOST'], $res))
{
   $subdomain = strtolower($res[1]);

   if(in_array($subdomain, $legitSubdomains))
   {
     $configsRootPath.= $subdomain . '/';
   }
}

require($configsRootPath . 'config.php');

PHP:

 

Hm. Maybe that can work. I'll have to have a look see and see if I can change stuff around a bit

 

Thanks. I got it working, now I just need to adjust a few parameters so uploaded files and such are kept together with the subdomain-folders.
