◆ getLanguages()

ilObjLanguageFolder::getLanguages ( )

gather all information about available languages

This function builds an array with the following structure: $languages[lang_key][long][installed][update][info]

lang_key: string international language key (2 digits, i.e. de,en,dk...) long: string full language name in the chosen user language installed: boolean is the language installed (true) or not (false)? update: int contains the timestamp of last db-modification info: string optional information. valid is: 'notfound','new'

Returns $languages status information about available languages
