   Hi
   
   when i try to use an IP function in my own script using the HTTP_X_FORWARDED_FOR variable, the ip showed by the variable is something like this : 69.147.251.52, 127.0.0.1 ?!
   
   why the HTTP_X_FORWARDED_FOR add the localhost ip 127.0.0.1 near the visitors IP ? is that can be fixed ?
   
   Thank you

   Create a php file with the following content:
   
   

   <?PHP
   echo "<pre>";
   print_r($_SERVER);
   echo "</pre>";
   ?>

   
   
   With this little script, you'll see all useable server variables and their contents. Dunno, what you want to fetch, but HTTP_X_FORWARDED_FOR is not accurate.
   
   If you specify your request a little bit more, we can try to find a solution, if the code above does not return the expected result.

   i use this php code to get visitors IP's :
   
   if (getenv(HTTP_X_FORWARDED_FOR))
   {
   $ip=getenv(HTTP_X_FORWARDED_FOR);
   }
   elseif(getenv(HTTP_CLIENT_IP)){
   $ip=getenv(HTTP_CLIENT_IP);
   }else{ $ip=getenv(REMOTE_ADDR);
   }
   
   
   but the IP i get it looks like this : 69.147.251.52, 127.0.0.1 and this is not correct the correct ip is just the first part 69.147.251.52 but the server add the localhost IP which is "127.0.0.1", and the problem is with HTTP_X_FORWARDED_FOR variable and you can see that in phpinfo()
   
   the php file that you told me to create, what name should i give it to it ?
   
   thanks

   Whatever you like ;) You just need to run it and check the output.
   
   But the output of HTTP_X_FORWARDED_FOR is normal. The X-Forwarded for header might contain multiple addresses, comma separated, if the request was forwarded through multiple proxies.
   
   You could split it:
   
   

   <?php
     function getIPfromXForwarded()
     {
         $ipString = @getenv("HTTP_X_FORWARDED_FOR");
         $addr = explode(",", $ipString);
         return $addr[sizeof($addr) - 1];
     }
     
     if (@getenv("HTTP_X_FORWARDED_FOR")) {
         $ip = getIPfromXForwarded(HTTP_X_FORWARDED_FOR);
     } elseif (getenv("HTTP_CLIENT_IP")) {
         $ip = getenv("HTTP_CLIENT_IP");
     } else {
         $ip = getenv("REMOTE_ADDR");
     }
   ?>
