Zend_Db-如何使用Zend_Db_Table_Select的结果

Question

在当前项目中，我不得不使用Zend-Framework，但是我只能停留在特定的位置。 不幸的是，该框架的文档太糟糕了，目前对我没有任何帮助。 该解决方案可能非常简单，但我无法自行解决。

我只是想从我的数据库中获取一些东西，我尝试使用以下代码来实现：

BS_Model_Subshops.php：

class BS_Model_Subshops extends BS_Lib_Model
{
    protected $_name = 'shops';
    protected $_username = '';
    protected $_password = '';
    protected $_primary = 'id';
}

LoginController.php：

public function authAction() {
    $shop= new BS_Model_Subshops();
    $id= filter_var($this->getRequest()->getPost('id'));
    $db_content= $shop->select()->where('id= '.$id);
    Zend_Debug::dump($db_content);

    ... more code ...
}

结果，我得到以下对象（警告：传入大量对象）：

object(Zend_Db_Table_Select)#85 (7) {
["_info":protected] => array(10) {
    ["schema"] => NULL
    ["name"] => string(5) "shops"

现在，例如，我只想要名称或CSS路径。 我如何获得其中之一？ 尽管我以前曾与laravel一起工作，但我对Zend并不是很熟悉，并且由于它是如此复杂且没有示例的良好文档，因此我在理解它方面遇到了很大的问题。

如果重要的话，Web服务器将使用PHP 5.4和Zend-Framework 1.9。

您可以使用fetchAll来获取名称或CSS路径

尝试下面的代码。

public function authAction() {
    $shop= new BS_Model_Subshops();
    $id= filter_var($this->getRequest()->getPost('id'));
    $db_content = $shop->select()->where('id= '.$id);
    $result = $db_content->query()->fetchAll();
    foreach($result as $key=>$value){   
        echo "Name : ". $value->name;
        echo "</br>";
        echo "Css Path : ". $value->css_path;
    }
    Zend_Debug::dump($db_content);

    ... more code ...
}

您还可以使用rowset对象的toArray方法将一个rowset检索为一个Array。

$result = $db_content->query()->fetchAll();
$row_array = $result->toArray();
