Something like this could be:

$object->_items[index]->_productId

But if _items is private, you'll need a public getter or mess with Reflection classes. You can configure access to private property through ReflectionProperty. Try the following:

    $reflectionObject = new ReflectionObject($yourObject);
    $property = $reflectionObject->getProperty('_items');
    $property->setAccessible(true);
    $items = $property->getValue($yourObject);

If you need to access the private / protected class, you can simply use the magic__get method . In this case, the reflection would be overboard. Regardless of whether it uses reasonable sense to use magic methods in this case, it depends on your situation.

class MyClass
{
    private $_items;

    public function __get($prop)
    {
        if ($prop == '_items') {
            return $this->_items;
        }
        throw new OutOfBoundsException;
    }
}

UPDATE

, , . ArrayAccess $_items.

class MyClass implements ArrayAccess
{
    private $_items = array();

    public function __construct() {
        $this->_items = array(
            "one"   => 1,
            "two"   => 2,
            "three" => 3,
        );
    }
    public function offsetSet($offset, $value) {
        if (is_null($offset)) {
            $this->_items[] = $value;
        } else {
            $this->_items[$offset] = $value;
        }
    }
    public function offsetExists($offset) {
        return isset($this->_items[$offset]);
    }
    public function offsetUnset($offset) {
        unset($this->_items[$offset]);
    }
    public function offsetGet($offset) {
        return isset($this->_items[$offset]) ? $this->_items[$offset] : null;
    }
}

, , PHP ArrayObject , . $_items.

Try the following:
