How to set X-Forwarded-For in PHP to sent client IP with simplexml_load_file

Question

We have got the client real IP behind the proxy using X-Forwarded-For.

But now the issue is that when we are calling a web service using simplexml_load_file, the server hosting the web service gets the IP of our server and not the real client server.

So we need a way to set the IP in X-Forwarded-For header so that the webservice gets the IP of the client that means it will feel that the client IP has called the webservice.

Answer 1

One possibility would be to start using curl for communication with the web service, so that you'd be able to set the header value

$ip = '123.123.123.123'; // your client's IP Address
curl_setopt( $ch, CURLOPT_HTTPHEADER, array("REMOTE_ADDR: $ip",
                                            "X_FORWARDED_FOR: $ip"));
