PHP获取真实IP 模拟IP 隐藏IP 代理IP 伪装IP 高匿代理 普匿代理 透明代理IP

我粗略列举6种PHP业内、国际各大开源系统获取用户真实IP的案例(包括Magento Zencart Zend Framework Yii...国内的就不提了吧!通杀!):

PHP获取用户真实IP方法1:

<?php function GetIP(){
if(!empty($_SERVER["HTTP_CLIENT_IP"])){
  $cip = $_SERVER["HTTP_CLIENT_IP"];
}
elseif(!empty($_SERVER["HTTP_X_FORWARDED_FOR"])){
  $cip = $_SERVER["HTTP_X_FORWARDED_FOR"];
}
elseif(!empty($_SERVER["REMOTE_ADDR"])){
  $cip = $_SERVER["REMOTE_ADDR"];
}
else{
  $cip = "无法获取!";
}
return $cip;
}
echo GetIP();
?> 

PHP获取用户真实IP方法2:

<?php error_reporting (E_ERROR | E_WARNING | E_PARSE);
if($HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"]){
$ip = $HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"];
}
elseif($HTTP_SERVER_VARS["HTTP_CLIENT_IP"]){
$ip = $HTTP_SERVER_VARS["HTTP_CLIENT_IP"];
}
elseif ($HTTP_SERVER_VARS["REMOTE_ADDR"]){
$ip = $HTTP_SERVER_VARS["REMOTE_ADDR"];
}
elseif (getenv("HTTP_X_FORWARDED_FOR")){
$ip = getenv("HTTP_X_FORWARDED_FOR");
}
elseif (getenv("HTTP_CLIENT_IP")){
$ip = getenv("HTTP_CLIENT_IP");
}
elseif (getenv("REMOTE_ADDR")){
$ip = getenv("REMOTE_ADDR");
}
else{
$ip = "Unknown";
}
echo $ip;
?> 

 

 

 

PHP获取用户真实IP方法3:

 

<?php $iipp = $_SERVER["REMOTE_ADDR"];
echo $iipp ;
?> 

 

 

PHP获取用户真实IP方法4:

<?php $user_IP = ($_SERVER["HTTP_VIA"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] : $_SERVER["REMOTE_ADDR"];
$user_IP = ($user_IP) ? $user_IP : $_SERVER["REMOTE_ADDR"];
echo $user_IP
?> 

 

 

PHP获取用户真实IP方法5:

<?php function get_real_ip()
{
$ip=false;
if(!empty($_SERVER["HTTP_CLIENT_IP"])){
  $ip = $_SERVER["HTTP_CLIENT_IP"];
}
if (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])){
  $ips = explode (", ", $_SERVER['HTTP_X_FORWARDED_FOR']);
  if($ip){
   array_unshift($ips, $ip); $ip = FALSE;
  }
  for($i = 0; $i < count($ips); $i++){
   if (!eregi ("^(10|172\.16|192\.168)\.", $ips[$i])){
    $ip = $ips[$i];
    break;
   }
  }
}
return($ip ? $ip : $_SERVER['REMOTE_ADDR']);
}
echo get_real_ip();
?> 

 

 

PHP获取用户真实IP方法6:

 

<?php if(getenv('HTTP_CLIENT_IP')){
$onlineip = getenv('HTTP_CLIENT_IP');
}
elseif(getenv('HTTP_X_FORWARDED_FOR')){
$onlineip = getenv('HTTP_X_FORWARDED_FOR');
}
elseif(getenv('REMOTE_ADDR')){
$onlineip = getenv('REMOTE_ADDR');
}
else{
$onlineip = $HTTP_SERVER_VARS['REMOTE_ADDR'];
}
echo $onlineip;
?>

获取用户真实IP原理:

客官看完了业界常用的获取用户真实IP方法后,发现有个共同规律,主要核心就是

HTTP_CLIENT_IP

HTTP_X_FORWARDED_FOR

REMOTE_ADDR

不同的演变,只是代码兼容性罢了!

如何模拟用户真实IP?

问:如果可以伪造模拟HTTP_CLIENT_IP,伪造模拟HTTP_X_FORWARDED_FOR,伪造模拟REMOTE_ADDR,不就可以达到追踪不到用户真实IP的目的了么?

答:楼上理解完全正确!如果做到这样完全可以通杀99%的获取用户真实IP,以用户IP为标识的系统!

(curl、socket、fsocketopen、stream_socket_client):

如何模拟HTTP_CLIENT_IP?HTTP_CLIENT_IP可以模拟么?伪装HTTP_CLIENT_IP!

 

curl_setopt($curl, CURLOPT_HTTPHEADER, array (
            'Client_Ip: '.mt_rand(0, 255).'.'.mt_rand(0, 255).'.'.mt_rand(0, 255).'.'.mt_rand(0, 255),
));//优点:伪造成本低,通杀90%系统

 

如何模拟HTTP_X_FORWARDED_FOR?HTTP_X_FORWARDED_FOR可以模拟么?伪装HTTP_X_FORWARDED_FOR!

 

curl_setopt($curl, CURLOPT_HTTPHEADER, array (
            'X-Forwarded-For: '.mt_rand(0, 255).'.'.mt_rand(0, 255).'.'.mt_rand(0, 255).'.'.mt_rand(0, 255),
));//优点:伪造成本低,通杀90%系统

 

如何模拟REMOTE_ADDR?REMOTE_ADDR可以模拟么?伪装REMOTE_ADDR!

 

curl_setopt($curl, CURLOPT_PROXYTYPE, CURLPROXY_HTTP);
curl_setopt($curl, CURLOPT_PROXY, '1.1.1.1:8080');//自行百度获得普匿代理IP即可,高匿代理IP更佳!
//优点:通杀100%系统
