- * Get a message from either the content language or the user language.
+ * Get a message from either the content language or the user language. The fallback
+ * language order is the users language fallback union the content language fallback.
+ * This list is then applied to find keys in the following order
+ * 1) MediaWiki:$key/$langcode (for every language except the content language where
+ * we look at MediaWiki:$key)
+ * 2) Built-in messages via the l10n cache which is also in fallback order
*
* @param $key String: the message cache key
- * @param $useDB Boolean: get the message from the DB, false to use only
- * the localisation
- * @param bool|string $langcode Code of the language to get the message for, if
- * it is a valid code create a language for that language,
- * if it is a string but not a valid code then make a basic
- * language object, if it is a false boolean then use the
- * current users language (as a fallback for the old
- * parameter functionality), or if it is a true boolean
- * then use the wikis content language (also as a
- * fallback).
+ * @param $useDB Boolean: If true will look for the message in the DB, false only
+ * get the message from the DB, false to use only the compiled l10n cache.
+ * @param bool|string|object $langcode Code of the language to get the message for.
+ * - If string and a valid code, will create a standard language object
+ * - If string but not a valid code, will create a basic language object
+ * - If boolean and false, create object from the current users language
+ * - If boolean and true, create object from the wikis content language
+ * - If language object, use it as given
* @param $isFullKey Boolean: specifies whether $key is a two part key
* "msg/lang".
*
* @throws MWException
- * @return string|bool
+ * @return string|bool False if the message doesn't exist, otherwise the message
