Discussion on: An easy way to get the (real) client IP in PHP

I had the same problem. I used the "REMOTE_ADDR" method on my website and it was showing up my cloudflare ip address. I wanted to echo the users ip, so this answer helped me out a ton.

I'm going to use this with Symfony's HTTP Foundation like so:

use Symfony\Component\HttpFoundation\Request;

$request ??= Request::createFromGlobals();
$ip = $request->server->get(
            'HTTP_CLIENT_IP',
            $request->server->get(
                'HTTP_CF_CONNECTING_IP',
                $request->server->get(
                    'HTTP_X_FORWARDED',
                    $request->server->get(
                        'HTTP_X_FORWARDED_FOR',
                        $request->server->get(
                            'HTTP_FORWARDED',
                            $request->server->get(
                                'HTTP_FORWARDED_FOR',
                                $request->server->get('REMOTE_ADDR')
                            )
                        )
                    )
                )
            )
        );
