How to get clients ip in php

[E Guru]

I am having a problem with some server load sharing and getting the clients correct ip.
When I use xforwardedfor it gets the first machines ip (servers ip) and I use remote_addr it gets the 2nd machines ip.
I tried using ['HTTP_CLIENT_IP'] but it shows ip blank.

Does anyone know what I can use grab the ip from the users browser?

No, that does not work. The whole variable does not work.

Here is what they told me.
Its passed as a variable
"x-client-ip"
in unix if you want to set the log to read it, you would use this:
LogFormat "\"%{X-Client-IP}i\" %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined

Well, how would I get that in php?

If
$_SERVER['REMOTE_ADDR'] doesn't work, superglobals may be broken

Try:

$ip = getenv('REMOTE_ADDR');
echo $ip

$_server[http_pc_remote_addr]

No man, it works. It just doesn't get the correct ip.

Are you using a proxy?

Have you tried x-forwarded-client?

Not myself, but server seams thinks I am. That is why I am trying to grab the IP from the users browser.

Returns a 0

How about $_GET['x-client-ip']

No go, comes up blank. You would think that would do it though.

[E Guru]

This is the code I used

<?php

$RIGHT_IP = $_GET['x-client-ip'];

?>

<? echo "$RIGHT_IP"; ?>

[E Guru]

Here is what they just said also:
If it were in unix it would be
LogFormat "\"%{X-Client-IP}i\" %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined


Wtf does that mean?

[Quickdraw]

Have you tried echo phpinfo(); to see what might work?

I grabbed this function from php.net and added the echo.. maybe?

PHP Code:

function getip() {
   if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP"), "unknown"))
   $ip = getenv("HTTP_CLIENT_IP");

   else if (getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR"), "unknown"))
   $ip = getenv("HTTP_X_FORWARDED_FOR");

   else if (getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR"), "unknown"))
   $ip = getenv("REMOTE_ADDR");

   else if (isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], "unknown"))
   $ip = $_SERVER['REMOTE_ADDR'];

   else
   $ip = "unknown";

   return($ip);
} 
echo getip();

Quikdraw - I tried the phpinfo and found the variable that held the ip

You rock

Got it working

An easier way to do this is:

<?=$RIGHT_IP?>

So what was the variable?
