how do i extract a local client PC private IP address with PHP

[worldcomingtoanend]

I only know how to extract public ip addresses using this:

$_SERVER['REMOTE_ADDR'];     
$_SERVER['SERVER_ADDR'];       

but i need a way to extract a pc ip address...I need this to do a condition for a service available to the local intranet members.  thank you..

You can't with php because php is server side so it can't see the local lan for your client. You may be able to with javascript.

This might be of some use to you:

<?php
    if ($_SERVER["HTTP_X_FORWARDED_FOR"] != ""){
        $IP = $_SERVER["HTTP_X_FORWARDED_FOR"];
        $proxy = $_SERVER["REMOTE_ADDR"];
        $host = @gethostbyaddr($_SERVER["HTTP_X_FORWARDED_FOR"]);
    }else{
        $IP = $_SERVER["REMOTE_ADDR"];
        $host = @gethostbyaddr($_SERVER["REMOTE_ADDR"]);
    }
?>
