PHP获取真实IP及IP模拟方法解析
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 $onlineip; ?>
获取用户真实IP原理:
客官看完了业界常用的获取用户真实IP方法后,发现有个共同规律,主要核心就是
HTTP_CLIENT_IP
HTTP_X_FORWARDED_FOR
REMOTE_ADDR
不同的演变,只是代码兼容性罢了!
如何模拟用户真实IP?
问:如果可以伪造模拟HTTP_CLIENT_IP,伪造模拟HTTP_X_FORWARDED_FOR,伪造模拟REMOTE_ADDR,不就可以达到追踪不到用户真实IP的目的了么?
答:楼上理解完全正确!如果做到这样完全可以通杀99%的获取用户真实IP,以用户IP为标识的系统!
支招【LET采集技巧】(curl、socket、fsocketopen、stream_socket_client):
如何模拟HTTP_CLIENT_IP?HTTP_CLIENT_IP可以模拟么?伪装HTTP_CLIENT_IP!
curl_setopt($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
