The IntlIterator class
(PHP 5 >= 5.5.0, PHP 7, PHP 8)
Einführung
This class represents iterator objects throughout the intl extension
whenever the iterator cannot be identified with any other object provided
by the extension. The distinct iterator object used internally by the
foreach
construct can only be obtained (in the relevant part here) from
objects, so objects of this class serve the purpose of providing the hook
through which this internal object can be obtained. As a convenience, this
class also implements the Iterator interface,
allowing the collection of values to be navigated using the methods
defined in that interface. Both these methods and the internal iterator
objects provided to foreach are backed by the same
state (e.g. the position of the iterator and its current value).
Subclasses may provide richer functionality.
