Get WAN IP Address from PHP

[Anon]

Does anyone know how to get PHP to display the WAN (Wide Area Network) IP address?

I tried using the following code on my own computer:

echo $_SERVER['REMOTE_ADDR'];

but that returned 127.0.0.1.

TIA,

Hi David,

The scalar variable of $REMOTE_ADDR will always return the IP of the client.

echo "$REMOTE_ADDR\n";

will return the client's IP in dotted decimal whereas

echo $_SERVER['REMOTE_ADDR']; will return local host information.

Hope this helps,

Ben
