Magento问题？如何在表格中循环添加评论？

 $i=1;
    while($i<=2){
      $review->setEntityId($review->getEntityIdByCode(Mage_Review_Model_Review::ENTITY_PRODUCT_CODE))
          ->setEntityPkValue($product->getId())
          ->setStatusId(Mage_Review_Model_Review::STATUS_APPROVED)
          ->setCustomerId(Mage::getSingleton(\'customer/session\')->getCustomerId())
          ->setStoreId(Mage::app()->getStore()->getId())
          ->setStores(array(Mage::app()->getStore()->getId()))
          ->save();
      $i++;
    }

Mage::getModel(\'module/model\')
