You could probably get something like this working.

Code:

$this->load->helper(url);
$current_url = current_url();
$url = str_replace('http://domain.com/1/2/3/', '', $current_url);

tnx i do this

Code:

$uri = $this->uri->uri_string();
   $url = explode("/", $uri, 4);
   $site = $url[3];
   $site2 = str_replace('http:/', 'http://', $site);

I add $site2 because for some reason the url[3] remove one / from http://

tnx for your help
