copy to clipboard

<?php

$array = array('1' => 'one',

               '2' => 'two',

               '3' => 'three');

$arrayobject = new ArrayObject($array);

}

Code Examples / Notes » arrayobject_construct

Note that the first argument to ArrayObject::__construct, the initial array, is passed by reference. Nevertheless, modification of the array doesn't modify the object, so it may cause unexpected behaviour. <?php $array = array('foo' => 'initial'); $obj = new ArrayObject($array); // array was passed by reference: $obj['foo'] = 'modified'; var_dump($array); // foo => modified // but it doesn't work backwards: $array['foo'] = 'modified_again'; var_dump($obj); // foo => modified var_dump($array); // foo => modified_again ?>
