If you want to use built-in array function with ArrayObject, store the iterator instance and return the value as reference in offsetGet.
<?php
class Collection extends \ArrayObject {
public function __construct(array $data = [])
{
if (!\is_array($data) && !\array_key_exists('ArrayAccess', class_implements($data))) {
$data = [$data];
}
$this->iterator = $this->getIterator();
parent::__construct($data);
}
public function &offsetGet($index)
{
$value = &$this->iterator[$index] ?? null;
return $value;
}
}
?>
