Apache2/PHP configuration problem: $_SERVER['REMOTE_ADDR'] fails

Hello all,

I've recently been getting into PHP to build a website for a Minecraft server I'm running. I've been understanding most of the code, and it's been working well from the snippets of info I get off of various sites... until this.

I'm building a MySQL database to store unique IP addresses, along with referrer and browser. After these variables are defined, the information is sent via PHP to my server. I was able to get these working:

$BROWSER = $_SERVER['HTTP_USER_AGENT'];
$REFERER = $_SERVER['HTTP_REFERER'];

PHP:

But when I try to get a user's IP address, I always get 192.168.1.64, no matter what I try.

Some general questions hopefully answered:
1: I'm testing it externally, this is irrelevant to my local address.
2: My local address is a static 192.168.1.111, so I'm absolutely sure it's not a local address mixup.
3: My local IP is set static by my router, and I have dyndns port forwarding to my external IP, which is also static.
4: I have the MySQL query working properly, it is not causing trouble.
5: I understand PHP and a bit of Apache, but code still needs explaining.
6: I have searched for weeks on how this works, and have tinkered with my code the entire time.
7: I'm assuming it's a problem with my Apache setup, but I am unclear on how to check/fix this.

Overall, my question is... WHAT am I doing WRONG?

 

I might add that the MySQL IP column in the table is a unique key, to avoid counting an IP more than once. In case somebody points that out

 

Thanks for all your help, useless forum
