PHP uses curl to forge IP and source

I haven't done this before.

A friend of the group is asking this question today.

Check it out, curl is really tough to forge IP and source.

1.php request 2.php.

1.php Code:

$ch = Curl_init (); curl_setopt ($ch, Curlopt_url, "http://localhost/2.php"); curl_setopt ($ch, Curlopt_httpheader, array (' x-forwarded-for:8.8.8.8 ', ' client-ip:8.8.8.8 '));  Tectonic ipcurl_setopt ($ch, Curlopt_referer, "http://www.gosoa.com.cn/");   Tectonic Route curl_setopt ($ch, Curlopt_header, 1); $out = Curl_exec ($ch); Curl_close ($ch);

The 2.php code is as follows:

function Getclientip () {    if (!empty ($_server["Http_client_ip"))        $ip = $_server["Http_client_ip"];    else if (!empty ($_server["http_x_forwarded_for"))        $ip = $_server["Http_x_forwarded_for"];    else if (!empty ($_server["REMOTE_ADDR"))        $ip = $_server["REMOTE_ADDR"];    else        $ip = "err";    return $IP;} echo "IP:". Getclientip (). ""; echo "Referer:". $_server["Http_referer"];

Forgery success, this is not to "brush ticket" friends to provide a very good scheme for IP change!!

Ha ha.

Someone message: You forged in the other side does not have a proxy IP and remote_addr the effect of blocking at the same time.
