- Since

Abstract base interface that cannot be implemented alone. Instead it must be implemented by either IteratorAggregate or Iterator.

- Internal classes that implement this interface can be used in a foreach construct and do not need to implement IteratorAggregate or Iterator.

This is an engine internal interface which cannot be implemented in PHP scripts. Either IteratorAggregate or Iterator must be used instead.
