【记事本】PHP获取IP地址的几种方法

PHP获取IP地址的几种方法！（来源网络）

方法一：

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

 

方法二：

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

 

方法三：

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

 

方法四：

<?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
 ?>

 

方法五：

<?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();
 ?>

 

方法六：

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