Manual => http://www.php.net/manual/en/ref.session.php
The function session_start(); must be executed prior to any headers sent on
any script you wish to call the session variables into. Typically you would
simply put session_start(); as the first line of each page. So..
----------------------------------
<? // page1.php
session_start();
$myvar = 'hello world';
session_register('myvar');
?>
<a href="page2.php">Page 2</a>
-------------------------------------
<? // page2.php
session_start();
// .. with registered globals ON
echo $myvar;
// .. or with reg globals OFF and before v4.1
echo $HTTP_SESSION_VARS['myvar'];
// .. or with reg globals OFF and after v4.1
echo $_SESSION['myvar'];
?>
------------------------------------
Hope this helps.
