No content of created file

I'm making a "MySQL free" login script. After encoding the login info and checking it against pre-encoded info, my scripts suppose to make a file. Its suppose to be named the IP address of the user, and its suppose to contain the username of the user.

It calls the file ".txt" instead of "76.114.191.116.txt" (76.114.191.116 is my ip address)


Heres my script:

<?php

//get input data
$user=$_POST["username"];
$pass=$_POST["password"];

//encrypt username and pass
$cuser=md5($user);
$cpass=md5($pass);

//include login file
include $user . ".php";

//make sure info matches and changes user's logged in file to ip
if ($cuser==$realuser && $cpass==$realpass)
{
$File = $REMOTE_ADDR . ".txt";
$Handle = fopen($File, 'w');
$Data = $user;
fwrite($Handle, $Data);
fclose($Handle);
header( 'Location: main.php' );
}
else
{
echo "Your login info was incorrect. Please wait, Redirectin...";
header ( 'location: index.htm' );
}

?>


Why is it doing this and how can i fix it???!!!

 

change

$File = $REMOTE_ADDR . ".txt";
//to
$File = $_SERVER['REMOTE_ADDR'] . ".txt";

PHP:
