php获取到两个ip
下面是使用fsockopen伪造ip。
<br> $out = "POST $path HTTP/1.1\r\n";<br> $out .= "Accept: */*\r\n";<br> $out .= "Content-Type: application/x-www-form-urlencoded\r\n";<br> $out .= "User-Agent: $_SERVER[HTTP_USER_AGENT]\r\n";<br> $out.="X-Forwarded-For: ".$ip."\r\n"; //主要是这里来构造IP<br> $out .= "Host: ".$domain_ip."\r\n";<br> $out .= "Content-Length: ".$content_length."\r\n";<br> $out .= "Connection: close\r\n\r\n";<br> $out .= $content."\r\n\r\n"; //提交的内容<br>
这个是获得客户端ip。本地可以获得伪造的ip，服务器上获得却是两个ip。比如变成这样116.7.54.78, 27.151.95.121。求帮忙
<br>
if (getenv("HTTP_X_FORWARDED_FOR")) <br>
{ <br>
$ip = getenv("HTTP_X_FORWARDED_FOR"); <br>
} <br>
elseif (getenv("HTTP_CLIENT_IP")) <br>
{ <br>
$ip = getenv("HTTP_CLIENT_IP"); <br>
} <br>
elseif (getenv("REMOTE_ADDR"))<br>
{ <br>
$ip = getenv("REMOTE_ADDR"); <br>
} <br>
else <br>
{ <br>
$ip = ""; <br>
} <br>
