php如何访问对象数组

如何从以下对象数组访问项数组

Cart66Cart Object
(
[_items:Cart66Cart:private] => Array
    (
        [2] => Cart66CartItem Object
            (
                [_productId:Cart66CartItem:private] => 327
                [_quantity:Cart66CartItem:private] => 3
                [_optionInfo:Cart66CartItem:private] => 
                [_priceDifference:Cart66CartItem:private] => 0
                [_customFieldInfo:Cart66CartItem:private] => 
                [_productUrl:Cart66CartItem:private] => http://localhost/odesk/cart66/fran-wilson-aloe-lip-care/
                [_formEntryIds:Cart66CartItem:private] => Array
                    (
                    )

            )

        [3] => Cart66CartItem Object
            (
                [_productId:Cart66CartItem:private] => 368
                [_quantity:Cart66CartItem:private] => 2
                [_optionInfo:Cart66CartItem:private] => 
                [_priceDifference:Cart66CartItem:private] => 0
                [_customFieldInfo:Cart66CartItem:private] => 
                [_productUrl:Cart66CartItem:private] => http://localhost/odesk/cart66/beauty-strokes-basic-shadow-brush/
                [_formEntryIds:Cart66CartItem:private] => Array
                    (
                    )

            )

    )

[_promotion:Cart66Cart:private] => 
[_promoStatus:Cart66Cart:private] => 0
[_shippingMethodId:Cart66Cart:private] => 13
[_liveRates:Cart66Cart:private] => Cart66LiveRates Object
    (
        [toZip] => 
        [weight] => 
        [rates] => Array
            (
            )

        [_toCountryCode:protected] => 
    )

)

这样的事情可能是：

$object->_items[index]->_productId

但是如果_items是私有的,你将需要一个公共的getter或者使用Reflection类.您可以将private属性设置为可通过ReflectionProperty访问
尝试这个：

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