PHP ca_metadata_elements::getPreferredDisplayLabelsForIDs方法代码示例

 /**
  * Returns all elements in system as list
  *
  * @param $pb_root_elements_only boolean If true, then only root elements are returned; default is false
  * @param $pm_table_name_or_num mixed Optional table name or number to filter list with. If specified then only elements that have a type restriction to the table are returned. If omitted (default) then all elements, regardless of type restrictions, are returned.
  * @param $pm_type_name_or_id mixed Optional type code or type_id to restrict elements to.  If specified then only elements that have a type restriction to the specified table and type are returned. 
  * @param $pb_use_cache boolean Optional control for list cache; if true [default] then the will be cached for the request; if false the list will be generated from the database. The list is always generated at least once in the current request - there is no inter-request caching
  * @param $pa_data_types array Optional list of element data types to filter on.
  *
  * @return array A List of elements. Each list item is an array with keys set to field names; there is one additional value added with key "display_label" set to the display label of the element in the current locale
