Here is a working example how to switch between sessions:

session_id('my1session');
session_start();
echo ini_get('session.name').'<br>';
echo '------------------------<br>';
$_SESSION['value'] = 'Hello world!';
echo session_id().'<br>';
echo $_SESSION['value'].'<br>';
session_write_close();
session_id('my2session');
session_start();
$_SESSION['value'] = 'Buy world!';
echo '------------------------<br>';
echo session_id().'<br>';
echo $_SESSION['value'].'<br>';
session_write_close();
session_id('my1session');
session_start();
echo '------------------------<br>';
echo $_SESSION['value'];

Log will look like:

PHPSESSID
------------------------
my1session
Hello world!
------------------------
my2session
Buy world!
------------------------
Hello world!

So, as you can see, session variables saved and restored while changing session.
