The variables $languages_id, $languages_name, and $languages_code provide us with the current language
in online shops based on osCommerce (osC). As the names suggest, $languages_id provides the identifier of the current language, $languages_name provides the name of the language (e.g. "German", "English"), and $languages_code provides the language and country code (e.g. "de_DE", "en_US").
