(PHP 5, PHP 7, PHP 8)

ArrayObject::__construct — Construct a new array object

### 说明

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

This constructs a new array object.

### 参数

`array`

  The `array` parameter accepts an array or an Object.

`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.

### 示例

示例 #1 ArrayObject::__construct() example

    <?php

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

    $arrayobject = new ArrayObject($array);

    var_dump($arrayobject);

    ?>

以上示例会输出：

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