1 menu.inc menu_get_item($path = NULL, $router_item = NULL)

Gets a router item.

Parameters

$path: The path; for example, 'node/5'. The function will find the corresponding node/% item and return that. Defaults to the current path.

$router_item: Internal use only.

Return value

array|FALSE The router item or, if an error occurs in _menu_translate(), FALSE. A router item is an associative array corresponding to one row in the menu_router table. The value corresponding to the key 'map' holds the loaded objects. The value corresponding to the key 'access' is TRUE if the current user can access this page. The values corresponding to the keys 'title', 'page_arguments', 'access_arguments', and 'theme_arguments' will be filled in based on the database values and the objects loaded.
