Detailed Description

language handling

language handling for setup

this class offers the language handling for an application. it works initially on one file: languages.txt from this file the class can generate many single language files. the constructor is called with a small language abbreviation e.g. $lng = new Language("en"); the constructor reads the single-languagefile en.lang and puts this into an array. with e.g. $lng->txt("user_updated"); you can translate a lang-topic into the actual language

Todo:
Das Datefeld wird bei Aenderungen einer Sprache (update, install, deinstall) nicht richtig gesetzt!!! Die Formatfunktionen gehoeren nicht in class.Language. Die sind auch woanders einsetzbar!!! Daher->besser in class.Format

Todo:
The DATE field is not set correctly on changes of a language (update, install, your stable). The format functions do not belong in class.Language. Those are also applicable elsewhere. Therefore, they would be better placed in class.Format

This function checks if a lang-file of a given lang_key exists, the file has a header, and each lang-entry consists of exactly three elements (module, identifier, value).

Parameters
string$a_lang_keyinternational language key (2 digits)
string$scopeempty (global) or "local"
Returns
string $info_text message about results of check OR "1" if all checks successfully passed
