The Iterator interface(PHP 5, PHP 7, PHP 8) Show IntroductionInterface for external iterators or objects that can be iterated themselves internally.

ExamplesExample #1 Basic usage This example demonstrates in which order methods are called when using foreach with an iterator.
__construct() { The above example will output something similar to: string(18) "myIterator::rewind" string(17) "myIterator::valid" string(19) "myIterator::current" string(15) "myIterator::key" int(0) string(12) "firstelement" string(16) "myIterator::next" string(17) "myIterator::valid" string(19) "myIterator::current" string(15) "myIterator::key" int(1) string(13) "secondelement" string(16) "myIterator::next" string(17) "myIterator::valid" string(19) "myIterator::current" string(15) "myIterator::key" int(2) string(11) "lastelement" string(16) "myIterator::next" string(17) "myIterator::valid" Table of Contents
