         * Sets a value

         * @param   string   $name      Name of the value to set.
         * @param   mixed    $value     Value to assign to the input.
         * @param   integer  $expire    The time the cookie expires. This is a Unix timestamp so is in number
         *                              of seconds since the epoch. In other words, you'll most likely set this
         *                              with the time() function plus the number of seconds before you want it
         *                              to expire. Or you might use mktime(). time()+60*60*24*30 will set the
         *                              cookie to expire in 30 days. If set to 0, or omitted, the cookie will
         *                              expire at the end of the session (when the browser closes).
         * @param   string   $path      The path on the server in which the cookie will be available on. If set
         *                              to '/', the cookie will be available within the entire domain. If set to
         *                              '/foo/', the cookie will only be available within the /foo/ directory and
         *                              all sub-directories such as /foo/bar/ of domain. The default value is the
         *                              current directory that the cookie is being set in.
         * @param   string   $domain    The domain that the cookie is available to. To make the cookie available
         *                              on all subdomains of example.com (including example.com itself) then you'd
         *                              set it to '.example.com'. Although some browsers will accept cookies without
         *                              the initial ., RFC 2109 requires it to be included. Setting the domain to
         *                              'www.example.com' or '.www.example.com' will make the cookie only available
         *                              in the www subdomain.
         * @param   boolean  $secure    Indicates that the cookie should only be transmitted over a secure HTTPS
         *                              connection from the client. When set to TRUE, the cookie will only be set
         *                              if a secure connection exists. On the server-side, it's on the programmer
         *                              to send this kind of cookie only on secure connection (e.g. with respect
         *                              to $_SERVER["HTTPS"]).
         * @param   boolean  $httpOnly  When TRUE the cookie will be made accessible only through the HTTP protocol.
         *                              This means that the cookie won't be accessible by scripting languages, such
         *                              as JavaScript. This setting can effectively help to reduce identity theft
         *                              through XSS attacks (although it is not supported by all browsers).
