  2. $iipp=$_SERVER["REMOTE_ADDR"];
  3. echo $iipp;
  4. ?>
复制代码

第二种方法：

  3. $user_IP = ($_SERVER["HTTP_VIA"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] : $_SERVER["REMOTE_ADDR"];

  4. $user_IP = ($user_IP) ? $user_IP : $_SERVER["REMOTE_ADDR"];

  5. echo $user_IP;

  6. ?>

复制代码

  4. function get_real_ip(){
  5. $ip=false;
  6. if(!empty($_SERVER["HTTP_CLIENT_IP"])){
  7. $ip = $_SERVER["HTTP_CLIENT_IP"];
  8. }
  9. if (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
  10. $ips = explode (", ", $_SERVER['HTTP_X_FORWARDED_FOR']);
  11. if ($ip) { array_unshift($ips, $ip); $ip = FALSE; }
  12. for ($i = 0; $i < count($ips); $i++) {
  13. if (!eregi ("^(10|172.16|192.168).", $ips[$i])) {
  14. $ip = $ips[$i];
  15. break;
  16. }
  17. }
  18. }
  19. return ($ip ? $ip : $_SERVER['REMOTE_ADDR']);
  20. }

  21. echo get_real_ip();

  22. ?>

复制代码

第三处方法：

  2. //php获取ip的算法
  3. if ($HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"])
  4. {
  5. $ip = $HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"];
  6. }
  7. elseif ($HTTP_SERVER_VARS["HTTP_CLIENT_IP"])
  8. {
  9. $ip = $HTTP_SERVER_VARS["HTTP_CLIENT_IP"];
  10. }
  11. elseif ($HTTP_SERVER_VARS["REMOTE_ADDR"])
  12. {
  13. $ip = $HTTP_SERVER_VARS["REMOTE_ADDR"];
  14. }
  15. elseif (getenv("HTTP_X_FORWARDED_FOR"))
  16. {
  17. $ip = getenv("HTTP_X_FORWARDED_FOR");
  18. }
  19. elseif (getenv("HTTP_CLIENT_IP"))
  20. {
  21. $ip = getenv("HTTP_CLIENT_IP");
  22. }
  23. elseif (getenv("REMOTE_ADDR"))
  24. {
  25. $ip = getenv("REMOTE_ADDR");
  26. }
  27. else
  28. {
  29. $ip = "Unknown";
  30. }
  31. echo "你的IP:".$ip ;
  32. ?>
复制代码

第四种方法：

  2. if(getenv('HTTP_CLIENT_IP')) {
  3. $onlineip = getenv('HTTP_CLIENT_IP');
  4. } elseif(getenv('HTTP_X_FORWARDED_FOR')) {
  5. $onlineip = getenv('HTTP_X_FORWARDED_FOR');
  6. } elseif(getenv('REMOTE_ADDR')) {
  7. $onlineip = getenv('REMOTE_ADDR');
  8. } else {
  9. $onlineip = $HTTP_SERVER_VARS['REMOTE_ADDR'];
  10. }
  11. echo $onlineip;
  12. ?>
