Anyone know why $REMOTE_HOST may not return any data?
Php running on Linux with Apache. Do I have to do something more?

    Whether such a predefined variable is available or not depends on the server.

    It could also be that you need to use $_SERVER['REMOTE_HOST']
    conversely, it could be that you should be using some other variable for what you want.

      I want to return the clients IP and HOST information. Supposedtly $REMOTE_ADDR; and $REMOTE_HOST; are the ones. any other recommendations?

        Maybe you don't have register_globals on. Try laserlight's suggestion of using the $SERVER array, i.e. $SERVER['REMOTE_HOST'] and $_SERVER['REMOTE_ADDR'].

          try this print_r ($GLOBALS);
          this will give you all the variables in the array

            I may not be able to answer your question but I did try what you suggested.

            I can access the client's IP address using REMOTE_ADDR but REMOTE_HOST is not printed in the list of globals when i use the

            print_r($GLOBALS);

            It does however give us the IP address as well as user agent.

            i think it has something to do with the DNS settings.

            Chances are if you have a dynamic IP address, your system might not have a hostname to show, therefore your REMOTE_HOST would not be set.

              Remote_host is available for my ip because Ive tested it with the php machine running on a diffrent server.

              When doing print_r($GLOBALS); its also not part of the list.

              $_SERVER('REMOTE_HOST')...etc doesnt work either.

              Whats causing this variable to not return data? is it server settings.? or what?

                $_SERVER('REMOTE_HOST')...etc doesnt work either.

                It's $SERVER['REMOTE_HOST'], not $SERVER('REMOTE_HOST')

                Whats causing this variable to not return data? is it server settings.? or what?

                Check your register_globals setting in php.ini.

                  $_SERVER('REMOTE_HOST') this was a typo in my post

                  I tried this and it didnt work.
                  $_SERVER['REMOTE_HOST']

                  None of these work:
                  $whatever = getenv("REMOTE_HOST");
                  $whatever = $_SERVER['REMOTE_HOST']

                  $whatever = $REMOTE_HOST;

                  and when I do
                  $_ENV['REMOTE_HOST'];

                  it returns
                  " localhost "
                  ?????/

                  What is the specific setting in php.ini to enable REMOTE_HOST to "register"?

                    I GOT IT. yessssssssssssssss.

                    $wooz = gethostbyaddr($_SERVER['REMOTE_ADDR']);
