    session_unregister

    (PHP 4, PHP 5 < 5.4.0)

    session_unregister — Unregister a global variable from the current session

    Description

    bool session_unregister ( string $name )

    session_unregister() unregisters the global variable named name from the current session.

    Warning

    This function has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 5.4.0.

    Parameters

    name

    The variable name.

    Return Values

    Returns TRUE on success or FALSE on failure.

    Notes

    Note:

    If $_SESSION (or $HTTP_SESSION_VARS for PHP 4.0.6 or less) is used, use unset() to unregister a session variable. Do not unset() $_SESSION itself as this will disable the special function of the $_SESSION superglobal.

    Caution

    This function does not unset the corresponding global variable for name, it only prevents the variable from being saved as part of the session. You must call unset() to remove the corresponding global variable.

    Caution

    If you are using $_SESSION (or $HTTP_SESSION_VARS), do not use session_register(), session_is_registered() and session_unregister().

    If globals is on, you'll have to unset the $_SESSION[varname] as well as the $varname.

    Like:

    unset($_SESSION[varname]);
    unset($varname);

    as a side note you must have session_start() set inorder to actually unregister the session varibles.
