This list is for the development of PHP, rather than its usage. If you
have further questions please submit them to the php-general list, or
one of the other lists at:

   http://www.php.net/support.php

In answer to your question, take a look at:

   http://www.php.net/manual/html/function.gethostbyaddr.html

You don't need to use getenv() with php, the $REMOTE_ADDR variable
should already be defined in the global context. If you want to see it
from inside a function, you will need to use a global declaration.

You might be able to enable hostname lookups on your web server and use
the HTTP_HOST variable, but unless you need it on every page served it
is a waste of time.
