note 22874 added to ref.url

If you want to check if a variable was passed in the querystring (ie., <url>?var=value&...), but don't want to use 'isset($var)' because maybe the var is in the session (and so you can get wrong 'true's), use the $_GET array. For example: isset($_GET['var']) == TRUE if var in querystring, but isset($_GET['var']) == FALSE if var in session and not in querystring -- http://www.php.net/manual/en/ref.url.php http://master.php.net/manage/user-notes.php?action=edit+22874 http://master.php.net/manage/user-notes.php?action=delete+22874 http://master.php.net/manage/user-notes.php?action=reject+22874
