validate the logical structure of a lang-file
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_key international language key (2 digits) string $scope empty (global) or "local"
- Returns:
- string $info_text message about results of check OR "1" if all checks successfully passed
