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

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

A string is a sequence of characters, including letters, numbers, and symbols. This tutorial will learn how to calculate the number of vowels in a given string in PHP using different methods. The vowels in English are a, e, i, o, u, and they can be uppercase or lowercase. What is a vowel? Vowels are alphabetic characters that represent a specific pronunciation. There are five vowels in English, including uppercase and lowercase: a, e, i, o, u Example 1 Input: String = "Tutorialspoint" Output: 6 explain The vowels in the string "Tutorialspoint" are u, o, i, a, o, i. There are 6 yuan in total

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.
