PHP Manual: ArrayObject::_

Description

public function ArrayObject::__construct(array|object $array = [], int $flags = 0, string $iteratorClass = ArrayIterator::class)

This constructs a new array object.

Warning

As of PHP 8.5.0, passing an enum as the array parameter throws an InvalidArgumentException. Modifying the $name or $value properties of an enum would break engine assumptions.

Parameters

array: The array parameter accepts an array or an object. Passing an object is deprecated as of PHP 8.5.0.
flags: Flags to control the behaviour of the ArrayObject object. See ArrayObject::setFlags().
iteratorClass: Specify the class that will be used for iteration of the ArrayObject object. The class must be a subtype of the ArrayIterator class.

Errors/Exceptions

As of PHP 8.5.0, throws an InvalidArgumentException if array is an enum.

Changelog

Version	Description

Examples

Example #1 ArrayObject::__construct() example

<?php

$array = [
    '1' => 'one',
    '2' => 'two',
    '3' => 'three'
];

$arrayobject = new ArrayObject($array);

var_dump($arrayobject);

?>

The above example will output:

object(ArrayObject)#1 (1) {
  ["storage":"ArrayObject":private]=>
  array(3) {
    [1]=>
    string(3) "one"
    [2]=>
    string(3) "two"
    [3]=>
    string(5) "three"
  }
}
