The menu system uses serialized arrays stored in the database for arguments. However, often these need to change according to the current path. This function unserializes such an array and does the necessary change.

Integer values are mapped according to the $map parameter. For example, if unserialize($data) is array('view', 1) and $map is array('node', '12345') then 'view' will not be changed because it is not an integer, but 1 will as it is an integer. As $map[1] is '12345', 1 will be replaced with '12345'. So the result will be array('node_load', '12345').

Parameters

@data: A serialized array.

@map: An array of potential replacements.

Return value

The $data array unserialized and mapped.
