Description:
------------
function session_unset() reset local variables.
I was trying to reset session variables after storing two values from session. It reset my local variables. Lets take a look into the codes bellow.

Reproduce code:
---------------
session_start();
$message = sprintf('%s', $_SESSION['message']);

echo('Here Message: # ' . $message . '<br />');

session_unset();

echo('Here Message: # ' . $message . '<br />'); // in this line, the variable $message has been unset.

Expected result:
----------------
It should display the value of $message

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php


Note: If $_SESSION (or $HTTP_SESSION_VARS  for PHP 4.0.6 or less) is used, use unset() to unregister a session variable, i.e. unset ($_SESSION[\'varname\']);. 

session_unset() is to be ued when using register_globals() which is not advised.
