How to find the user's ip?

Question

PHP

There was always a standard code

function get_ip(){
    if (!empty($_SERVER['HTTP_CLIENT_IP'])) {
        $ip=$_SERVER['HTTP_CLIENT_IP'];
    } elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
        $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
    } else {
        $ip=$_SERVER['REMOTE_ADDR'];
    }
    return $ip;
}

I recently started using WARP. In theory, my ip should change at the same time. Looked at different services. Some of them determine my real ip without problems, and some determine ip cloudflare. And this standard script also determines ip cloudflare and how to determine the real ip?

Answer 1

The original visitor IP address appears in an appended HTTP header called CF-Connecting-IP . By following our webserver instructions, you can log the original visitor IP address at your origin server.

In PHP, look for this header here:
$_SERVER["HTTP_CF_CONNECTING_IP"]

Answer 2

There has always been a standard shit code that lamers all over the world diligently rewrite from each other, not understanding its meaning. Only
$ip=$_SERVER['REMOTE_ADDR']; should be left of it;
and the rest of the heresy in the trash.
