External PHP IP Logger

I have many PHP snippets on how to log IP's, but all they do is just log the external IP. Is there anyway to log an external IP, using PHP code?

This is the current PHP IP logger I have now, but it just logs the internal IP address, rather than the external IP.


<?php
 
$to = 'me@memail.com;
$subject = 'Visitors IP';
 
 
$visitorSpecs = 
"<hr size=2 width=300 align=left>".
"<b>Visitor IP address:</b> ".$_SERVER['REMOTE_ADDR'].
"<br>".
"<b>Visitor system specs:</b> ".$_SERVER['HTTP_USER_AGENT'].
"<br>";
 
$headers = "Content-type: text/html \nFrom: IP sniffer script";
 
$body = "<body>
<br>
<table cellspacing=1 cellpadding=2 align=center>
<tr>
<td>
<b><font face=arial size=2>Website visitors IP address and system specs:</font></b>
</td></tr>
<tr>
<td>
<font face=arial size=2> ".$visitorSpecs." </font>
</td></tr></table>
</body>";
 
mail($to,$subject,$body,$headers);
?>

if ($_SERVER['HTTP_X_FORWARD_FOR']) {
$ip = $_SERVER['HTTP_X_FORWARD_FOR'];
} else {
$ip = $_SERVER['REMOTE_ADDR'];

It's werid I added the snippet you gave me, but now it gives me a parse error:

Parse error: parse error in /home/l/login.siteburg.com/WWW/homepage.php on line 4

But it does not describe what the error is?

found was missing a "  '  " after my email address.

All I am getting in my email is, the inertnal IP not external. Why is that?

Website visitors IP address and system specs:  

--------------------------------------------------------------------------------
Visitor IP address: 198.173.4.9
Visitor system specs: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727; .NET CLR 3.0.04506; InfoPath.2)

I found the following code for external ips.

Can you insert it into my code for me.


/**
* Call as: $userp = GetUserIP();
*/
function GetUserIP() {
 
    if (isset($_SERVER)) {
 
        if (isset($_SERVER["HTTP_X_FORWARDED_FOR"]))
            return $_SERVER["HTTP_X_FORWARDED_FOR"];
        
        if (isset($_SERVER["HTTP_CLIENT_IP"]))
            return $_SERVER["HTTP_CLIENT_IP"];
 
        return $_SERVER["REMOTE_ADDR"];
    }
 
    if (getenv('HTTP_X_FORWARDED_FOR'))
        return getenv('HTTP_X_FORWARDED_FOR');
 
    if (getenv('HTTP_CLIENT_IP'))
        return getenv('HTTP_CLIENT_IP');
 
    return getenv('REMOTE_ADDR');
}

that's the ip that's used to directly connect to the server if both your client and the server are on the same internal subnet that might happen..
but as far as I can tell the 198 is not a privat ip range.

where's your server?
if you are testing on a server that is in your network the server would only see your internal ip..

try to do a phpinfo();
to see what variable holds the correct IP..
just upload a file with below code
don't forget to delete after you are done..

<?php
 
phpinfo();
 
?>

Would'nt you have to state the file location/name, of the phpinfo() in my base ip logging script?

Or just insert code in a new file and that should be good?

just create a new file ..
dump that line in . and call it from your browser..
it will give you a lot of info on the server and also what server vars are stored.. then when you find your ip you can use that info to change the script.

it's your hosting provider that's screwing up..
remote address and server address shouldn't be the same.. unless your working on their server ;)
ask your buddy to fix it...
