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 !
