30 * This function will always return a value of the same type as the default.
31 * @param bool $multibyte If $default is a string this paramater has to be true if the variable may contain any UTF-8 characters
32 * Default is false, causing all bytes outside the ASCII range (0-127) to be replaced with question marks
33 * @param bool $cookie This param is mapped to phpbb_request::COOKIE as the last param for phpbb_request::variable for backwards compatability reasons.
