Get hostname of domain alias

[spride]

Relatively new with PHP, so forgive me if this is a trivial question.
I have a site hosted with PHP. I'm thinking of getting another
hostname and alias it to this host. What I'd then like to do is have a
PHP file (i.e., index.php) that reads a variable from the request that
tells me which hostname is being served. I can then change the title
and whatnot of the returning HTML, depending on which hostname was
used. For example:

<?php
$HOSTNM = ???

if ( $HOSTNM == 'abcefg.com' )
$TITLE = 'ABCDEFG';
else
$TITLE = 'HIJKLM';

etc...
?>

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