Iam (Zend framework kullanarak) bir menü oluşturma (zend_navigation)

what iam doing is getting the page as label if the page has the value "myPage" than then iam setting the new URI with the page as expected

$it = new RecursiveIteratorIterator(
$container, RecursiveIteratorIterator::SELF_FIRST);

 foreach ($it as &$page) {
   $label = $page->label;
   if($label = "MyPage"){
    $newuri = "mypage.php?stcode=".$stcode."&cde=".$cde;            
    $page->setUri($newuri);
}           

}

In the above statement iam getting an error "An iterator cannot be used with foreach by reference". I want to use reference so that based on the label i can point the page to new uri

Şimdi benim sorunum ve menüsündeki tüm menü öğeleri aynı URI alıyorsanız.
