如何从对象（Zend_Db_Table_Rowset）中提取数据

Question

我有那个对象（Zend_Db_Table_Rowset）

object(Zend_Db_Table_Rowset)#183 (10) { ["_data":protected]=> array(1) { [0]=> array(18) { 
["panel_id"]=> string(2) "37" ["group_id"]=> string(2) "19" ["panel_language"]=> string(2) "en" 
["panel_name"]=> string(24) "IRAQI NATIONAL COMPANIES" ["panel_heading"]=> string(24) "IRAQI 
NATIONAL COMPANIES" ["panel_content"]=> string(404) "
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus turpis velit, egestas a venenatis 
at,pharetra at est. Suspendisse sagittis dapibus congue. Maecenas hendrerit, ipsum quis iaculis 
dignissim, leo enim varius diam,
iaculis pretium magna diam non velit. Etiam congue nisl sed quam lobortis ultricies. Vestibulum 
ipsum tellus, fermentum vel
tempor eu, blandit

并且我想得到panel_heading，panel_content

我正在尝试这样做

$panels->panel_heading;
$panels->panel_content;

我得到通知：

 Notice: Undefined property: Zend_Db_Table_Rowset::$panel_heading

是否有一种简单的方法来提取数据？

使用下面的代码：

foreach($panels as $panel)echo $panel->panel_content
