php之IP

 

常用的获取客户端的IP地址的方法: 

1) 

 1  function getRemoteIp(){
 2 
 3        if(isset($_SERVER['HTTP_X_FORWARDED_FOR'])){
 4 
 5             $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
 6  
 7        }
　　　　　　elseif(isset($_SERVER['HTTP_CLIENT_IP'])){
 8 
 9             $ip = $_SERVER['HTTP_CLIENT_IP'];
10 
11         }
　　　　　　elseif(getenv('HTTP_X_FORWARDED_FOR')){
12 
13             $ip = getenv('HTTP_X_FORWARED_FOR');
14 
15         }
　　　　　　elseif(getenv('HTTP_CLIENT_IP')){
16 
17             $ip = getenv('HTTP_CLIENT_IP');
18 
19         }
　　　　　　elseif($_SERVER['REMOTE_ADDR']){
20 
21             $ip = $_SERVER['REMOTE_ADDR'];
22 
23         }
24         else{
25 
26             $ip = null;
27     
28         }
29         
30         return $ip;
31     }
