Hi,

Try $_SERVER['SERVER_NAME'] or  $_SERVER['HTTP_HOST'].

It should do it.

You tried $_SERVER['HTTP_HOST'] too?
I used it many times and never let me down.
But if you still get the long version, you should use an explode with "/" and save only the first element.

$uri = explode("/", $_SERVER['HTTP_HOST']);
echo $uri[0];
