OK -- I've written a PHP class that is capable of extracting whichever
components you like out of a hostname, including its "effective TLD"
that is:

Host ETLD
--------------------------------------------
groups.google.co.uk. co.uk.
www.ealing.nhs.uk. nhs.uk.
www.ipart.nsw.gov.au. nsw.gov.au.
www.google.com. com.
www.last.fm. fm.
www.british-library.uk. uk.
del.icio.us. us.

The syntax for this is:

<?php
include "Domain.class.php";
$x = new Domain('www.ealing.nhs.uk');
echo $x->get_reg_domain()."\n"; // ealing.nhs.uk.
echo $x->get_etld()."\n"; // nhs.uk.
echo $x."\n"; // www.ealing.nhs.uk.
?>
