• CloudFlare and logging visitor IP addresses via in PHP 8 answers

How can I get the real ip address from the user, when using CloudFlares service?

I need the real ip for the user connecting, and using this:

 $_SERVER['REMOTE_ADDR'] = $_SERVER["HTTP_CF_CONNECTING_IP"] ? $_SERVER["HTTP_CF_CONNECTING_IP"] : $_SERVER["REMOTE_ADDR"]; 

Will only show my correct IP address, not the user connecting.
