PHP CRM_Utils_Hook::alterSettingsFolders方法代码示例

 /**
  * WARNING: This interface may change.
  *
  * This provides information about the setting - similar to the fields concept for DAO information.
  * As the setting is serialized code creating validation setting input needs to know the data type
  * This also helps move information out of the form layer into the data layer where people can interact with
  * it via the API or other mechanisms. In order to keep this consistent it is important the form layer
  * also leverages it.
  *
  * Note that this function should never be called when using the runtime getvalue function. Caching works
  * around the expectation it will be called during setting administration
  *
  * Function is intended for configuration rather than runtime access to settings
  *
  * The following params will filter the result. If none are passed all settings will be returns
  *
  * @param array $filters
  * @param int $domainID
  *
  * @return array
  *   the following information as appropriate for each setting
  *   - name
