note 9775 added to gethostbyaddr

This is a really usefull function.. I ussualy use it to know the name of the country that the host has.. (.pt, .es, .uk, etc).. here is a litle idea of what one can do with this.. I get the $ipa with the remote_addr function.. <? $host = gethostbyaddr($ipa); $at = $host $hostdot = "."; $result = strrchr($at, $hostdot); echo "The country is $result"; ?> Of course, if a .com or .org or .net domain name (tld) it won't be a country.. but you can work that out with and if or case statements.. and of course, I can be totally mistaken ;P http://www.php.net/manual/function.gethostbyaddr.php
