                               hw_InCollections

   (PHP 3>= 3.0.3, PHP 4 )
   hw_InCollections -- check if object ids in collections

Description

   array hw_incollections ( int connection, array object_id_array, array
   collection_id_array, int return_collections)

   Checks whether a set of objects (documents or collections) specified
   by the object_id_array is part of the collections listed in
   collection_id_array. When the fourth parameter return_collections is
   0, the subset of object ids that is part of the collections (i.e., the
   documents or collections that are children of one or more collections
   of collection ids or their subcollections, recursively) is returned as
   an array. When the fourth parameter is 1, however, the set of
   collections that have one or more objects of this subset as children
   are returned as an array. This option allows a client to, e.g.,
   highlight the part of the collection hierarchy that contains the
   matches of a previous query, in a graphical overview.
