Displaying domain name only in PHP without www. or / or anything else.. ?

The code below displays: domain.com/ but I would like to display just domain.com without the /

Code (text):

$hostname = $_SERVER[‘SERVER_NAME’]; $hostname = str_replace(‘www.’, ”, $hostname); echo $hostname . htmlentities($_SERVER[‘REQUEST_URI’]);

Also how would I display domain.com in all uppercase letters; DOMAIN.COM
Thanks in advance!
