The ArrayIterator class

(PHP 5, PHP 7, PHP 8)

Introduction

Allows the removal of elements, and the modification of keys or values while iterating over Arrays or Objects.

When you want to iterate over the same array multiple times you need to instantiate ArrayObject and let it create ArrayIterator instances that refer to it either by using foreach or by calling its getIterator() method manually.

Predefined Constants

ArrayIterator Flags
