List of iterator function in php
The Iterator interface(PHP 5, PHP 7, PHP 8) Show IntroductionInterface for external iterators or objects that can be iterated themselves internally. Interface synopsisPredefined iteratorsPHP already provides a number of iterators for many day to day tasks. See SPL iterators for a list. 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

__construct( $givenArray ) { What are the iterator functions?Iterator in Java is used to traverse each and every element in the collection. Using it, traverse, obtain each element or you can even remove. ListIterator extends Iterator to allow bidirectional traversal of a list, and the modification of elements.
Which of the following are the SPL iterators?SPL Iterators Class Tree ¶. AppendIterator.. CachingIterator. RecursiveCachingIterator.. FilterIterator. CallbackFilterIterator. RecursiveCallbackFilterIterator. RecursiveFilterIterator. ParentIterator. RegexIterator. RecursiveRegexIterator.. InfiniteIterator.. LimitIterator.. NoRewindIterator.. What is Iterable type?Iterable is a pseudo-type introduced in PHP 7.1. It accepts any array or object implementing the Traversable interface. Both of these types are iterable using foreach and can be used with yield from within a generator.
What is iterator in Java?An Iterator is an object that can be used to loop through collections, like ArrayList and HashSet. It is called an "iterator" because "iterating" is the technical term for looping. To use an Iterator, you must import it from the java. util package.
