I have tried over and over to log a person's IP secretly when they submit
my form data , how do I make the IP show up in my output file without
having any trouble , here's what I need done , I want a <input type="hidden" name="ip">
to go to the following file and displayed in the output html
file that is listed in the php code which is data.html
PHP Code:

<title>::ULTIMATE OFFSPRING:: Done</title>
<body bgcolor="000000">
<?php
$filename="data.html";
$handle=fopen($filename,'a');
$string="<hr>
<font color=\"blue\" font size=\"4\"> 
Name: <font color=\"red\" font size=\"3\"> 
$_POST[name] <br><br> <font color=\"blue\" font size=\"4\">
