The ArrayObject class

Introduction

(PHP 5, PHP 7, PHP 8)

This class allows objects to work as arrays.

Predefined Constants

ArrayObject Flags

ArrayObject::STD_PROP_LIST

Properties of the object have their normal functionality when accessed as list (var_dump, foreach, etc.).

ArrayObject::ARRAY_AS_PROPS

Entries can be accessed as properties (read and write).
