正如您所看到的，有2个[数量]值。如果我键入：
$this->Product['stock_item']['qty'] = 2；我可以访问第一个[数量]。我的问题是如何访问第二个〔数量〕？Thx
Magento为任何"数据"提供了神奇的getter和setter，所以你可以这样做来获取和设置"数量"：
$qty = $this->product->getQty();
$this->product->setQty($qty);
但是您也可以使用以下方法来获得阵列：
$dataArray = $this->product->getData();
$origDataArray = $this->product->getOrigData();
$this->product->setData($dataArray);
$this->product->setOrigData($origDataArray);
或者这是为了获得/设置一个特定的值：
$dataQty = $product->getData('qty');
$origDataQty = $product->getOrigData('qty');
$product->setData('qty', $dataQty);
$product->setOrigData('qty', $origDataQty);
