how to delete a session variable?

[mshen]

I need to delete the session variable when I logout a application.

Please let me know which function I can use to delete a session variable.Thanks.

You mean the whole session right?

Try:

session_destroy();

The contents of the $_SESSION[] array can be handled like the contents of any other array:

unset($_SESSION['doomed_variable']) is the obvious method. Prior to 4.3, though there was a bug which means that in earlier versions you'd need to use

$_SESSION['doomed_variable'] = null;

instead.
