unset() a session variable inside of a function

[rudenborg]

Hi-

I have what should be a simple question. I've searched through this forum and php.net and google and haven't found a satisfactory answer to it though.

What is the sure way to completely destroy (globaly) a session variable inside of a function.

as an example:

$_SESSION['blah'] = 'blah';

function blah()
{
// i need to delete $_SESSION['blah']
// what code should I use here???
}

// now any refference to $_SESSION['blah'] should return an error saying it doesn't exist.


Thanks!

What about:

unset ($_SESSION['blah']);

$_SESSION is a superglobal array, which means that it appears in every variable scope. You don't have to do anything special to $_SESSION (or $_POST, $_GET, etc.) to be able to manipulate it.
