Answer 1

You need to call session_start() again at beginning of the new file, like so:

<?php 
session_start();

echo "My Name is " . $_SESSION['uName'];

Answer 2

page1.php

<?php
session_start();
$_SESSION['uName'] = "Mike";
?>

page2.php

<?php
session_start();
echo "My Name is " . $_SESSION['uName'];
//eventually
unset($_SESSION['uName']);
?>

Answer 3

You need to add session_start(); to all files that use sessions.
