The MongoCursorInterface interface

(PECL mongo >=1.5.0)

Interface for cursors, which can be used to iterate through results of a database query or command. This interface is implemented by the MongoCursor and MongoCommandCursor classes.

Note: Similar to Traversable, this interface cannot be implemented in PHP scripts.
