I know I can use 

$_SERVER['REMOTE_ADDR'] 

to get a user's IP address.  However that only gives either the IPv4 or the IPv6 address, not both. 

I've seen sites that will give you both.  I'm wondering how to get both with PHP.  Is it some simple function I just don't know about or does it require some complex actions (If it requires something complex just point me in the right direction to get started)? 

Thanks in advance.

The way they do it is they give the user something to connect to that supports only IPv4, and then another that supports only IPv6. Then they combine the information together to give you the full results.

Because all you can ever get from the user is how they connected to your site. If they used IPv4 then you can't know what their (public) IPv6 address is.
