Get domain name

I needed to get the domain name only based on the base_url() function. I added the following function to the url_helper.php :

/**
 * Get domain
 *
 * Return the domain name only based on the "base_url" item from your config file.
 *
 * @access    public
 * @return    string
 */    

function getDomain()
{
    $CI =& get_instance();
    return preg_replace("/^[\w]{2,6}:\/\/([\w\d\.\-]+).*$/","$1", $CI->config->slash_item('base_url'));
}

So you can use it in your code in the same manner than site_url() or base_url()

Hope this help somebody !
