无法在magento中使用id方法加载2种产品

Question

朋友们，我想用id方法加载两个捆绑产品。这是我写的密码.

<?php
   $bundled = Mage::getModel('catalog/product');
   $stdid=$bundled->getIdBySku('123457');
   $compid=$bundled->getIdBySku('123458');

   /*get additional options of the each products*/
    $y=$bundled->load($compid);
    $selectionCollection_complete = $y->getTypeInstance(true)->getSelectionsCollection(
                $y->getTypeInstance(true)->getOptionsIds($y), $y);

    $x=$bundled->load($stdid);
    $selectionCollection_standard = $x->getTypeInstance(true)->getSelectionsCollection(
                $x->getTypeInstance(true)->getOptionsIds($x), $x);


     /*store the option head name to an array for future 
      reference*/            
     foreach($selectionCollection_standard as $std_opt)
     {
        $opt_std_hd_names.=$std_opt->getName()."<BR>";
     }
     foreach($selectionCollection_complete as $cmp_opt)
     {
       $opt_cmp_hd_names.=$cmp_opt->getName()."<BR>";
     }


     $display="<pre>".print_r($opt_std_hd_names."<br><br>".$opt_cmp_hd_names)."</pre>"
?>

但是我的问题是$opt_std_hd_names和$opt_cmp_hd_names返回相同的输出，它们是我首先加载的产品选项(在本例中是$y。如果我首先放置$x代码，那么它将显示$x的选项).the输出如下所示。

  output:

您可以看到输出是相同的。为什么会这样？？请给出你的建议

$bundled = Mage::getModel('catalog/product');

这是引用相同的模型对象，您在两个加载操作中都使用它。每次运行getIdBySku()方法时，模型的数据都会被覆盖，引用该模型的每个变量也将被更新。

尝试以这种方式实例化一个新对象或检索数据：

$stdid  = Mage::getModel('catalog/product')->getIdBySku('123457');
$compid = Mage::getModel('catalog/product')->getIdBySku('123458');
