Passing variables can best be done via the $_SESSION array. So in your case it is best to code as follows:
[php]Registration.php:
------------------
<?php
session_start();
$username=$_POST['t3'];
$_SESSION['username'] = $username;

Registration1.php:
------------------
<?php
session_start();
echo $_SESSION['username'];

update.php:
-----------
<?php
session_start();
$username = $_SESSION['username'];
echo $username;
[/php]
