Getting IP address from user

[sc]

Hi!

I'm new to PHP. I made a small survey form, a HTML page that submits a form to a PHP script, and I want to get the user's IP address, but the function GetHostByName ($REMOTE_ADDR) is returning the server's IP address!
Could someone help me?
Thanks in advance!

The reason it is returning the ip address is because that is what the function does... returns the ip address. If you want the actual hostname you need to use gethostbyaddr()

No, I don't want the hostname, I *want* the IP address. But I'm getting the IP address of the machine that is running PHP/MySQL (the server), not the client's IP address (that I want).

I need to get the IP address of the user accessing my survey form, but I don't know what is happening. The function GetHostByName ($REMOTE_ADDR) is returning the local server's IP, not the remote address.

Best regards,

Code: Select all

$r_hostname = gethostbyaddr($REMOTE_ADDR);
if ($REMOTE_ADDR == "$r_hostname") {
    ....
}

I simply use:

$ipaddress = getenv("REMOTE_ADDR");

and then echo it out or store it in a database or whatever.

In some situation than used virtual host or dynamic IP you get not correct IP or not get IP actually
