$REMOTE_HOST doesnt work...

Solari

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"?

Solari

I noticed that its returning it under "Apache Environment" in phpinfo.php .

here it is.
