    clearing out all $_SESSOIN variables?

    Hello,
    In a particular session, I set a bunch of $_SESSION vars. Is
    there any way of erasing/purging all of them in one fell swoop or must
    I iterate through each one or even list them out ...

    $_SESSION["a"] = "";
    $_SESSION["b"] = "";

    ..... etc.

    I'm using PHP 4. Thanks for your help, - Dave

          $_SESSION = Array ();

                  or use both? I think the manual uses that as an example.
