getting a users ip address??

[wapak777]

Hi. my browser ist telling me there are errors on line 3 and 4 for my code. It says summin like Notice: HTTP_CLIENT_IP and HTTP_X_FORWARDED_FOR are unidentified:

 

below is the code see if you can spot anything btw i copied down the code from beginner php tutorial 66 if you type that into youtube .

<?php

$http_client_ip = $_SERVER['HTTP_CLIENT_IP'];
$http_x_forwarded_for = $_SERVER['HTTP_X_FORWARDED_FOR'];
$remote_addr = $_SERVER['REMOTE_ADDR'];

if (!empty($http_client_ip)){
   $ip_addr = $http_client_ip;
   
}else if(!empty($http_x_forwarded_for)){
   $ip_addr = $http_x_forwarded_for;
}else{
   $ip_addr = $remote_addr;
}

echo $ip_addr;
?>

 

Thanks

 

MOD EDIT: code tags added.

When posting code, enclose it within

You need to check that the variables $_SERVER['HTTP_CLIENT_IP'] and $_SERVER['HTTP_X_FORWARDED_FOR'] exist before using them.

Yh I know I was thinking they didn't actually exist but i saw this guy making a tutorial was using them and he didn't get any errors... I gonna check again that he didn't require or include another script before using them. and btw sorry about not including the code tags around the code

They must of either configured php to not display errors or set error_reporting so it ignores notices.
