Get Domain & Subdomain from URL
preg_match('/^(?:www\.)?(?:(.+)\.)?(.+\..+)$/i', $_SERVER['HTTP_HOST'], $matches);
define('PROTOCOL', strtolower(substr($_SERVER['SERVER_PROTOCOL'],0,strpos($_SERVER['SERVER_PROTOCOL'],'/'))).'://');
define('SUBDOMAIN', $matches[1]);
define('DOMAIN', $matches[2]);
define('HERE', $_SERVER['REQUEST_URI']);
define('PROTOCOL', strtolower(substr($_SERVER['SERVER_PROTOCOL'],0,strpos($_SERVER['SERVER_PROTOCOL'],'/'))).'://');
define('SUBDOMAIN', $matches[1]);
define('DOMAIN', $matches[2]);
define('HERE', $_SERVER['REQUEST_URI']);
If you're at http://www.sub.domain.com/page, then:
PROTOCOL = http://
SUBDOMAIN = sub
DOMAIN = domain.com
HERE = /page

It can also be done using parse_url().

OMG, a legitamate comment! I didn’t know about parse_url, but with the above address, it gives:
Array
(
[scheme] => http
[host] => http://www.sub.domain.com
[path] => /page
)
No “sub” or “domain.com” which is what I was after when I wrote that. If your site uses addresses like username.domain.com or something, this can be helpful to have.
Thanks for the tip though
