function views_menu_reference_get_link_path_parents_hierarchy in Views Menu Reference 7

Returns the <$link_path>'s parent menu hierarchy. It describes the mlids in each depth that may be direct (0) or indirect (1..*) parent. The hierarchy is indexed by the depth and may contain the tree items from more than one menu item, because multiple menu items's may belong to one <$link_path>. The depth index consists of a numeric (0..1..2...) and a plus'sed key (0+..1+..2+) which represent the subtree items.

The function is the public variant which makes use of caching to speed things up on a second request.
