Zend_Db连接MySQL(附完整代码）

在看这些之前请确保你正确加载了PDO扩展。

作法是编辑php.ini
手动增加这两行（前面要没有分号;）：
extension=php_pdo.dll
extension=php_pdo_mysql.dll
然后要把extension_dir
指向php_pdo.dll及php_pdo_mysql.dll所在目录，如
extension_dir = "C:\php5\ext"

OK,let's go..

index.php 网站首页，也是唯一入口

$params = array ('host'     => '127.0.0.1',
                 'username' => 'root',
                 'password' => '123456',
                 'dbname'   => 'happycms');

$db = Zend_Db::factory('pdoMysql', $params);
Zend::register('db', $db);
?>

lib/App/Article.php

class App_Article {
        private $db;
        function App_Article() {
                $this->db = Zend::registry('db');
        }

        function listAll() {
                $result = $this->db->query('SELECT * FROM article');
                $rows = $result->fetchAll();

                Zend::dump($rows);
        }

        function listByCategory() {

ArticleController.php
class articleController extends Zend_Controller_Action  {
    private $view;
    private $article;

    function __construct() {               
        $this->view = Zend::registry('view');
        $this->article = new App_Article();       
    } 

    public function listAllAction() {
        $this->article->listAll();
        $this->view->title='View Articles';          
        echo $this->view->render(TPL_DIR.'/tplView.php');
    }

    function __call($action, $arguments)
    {       
        $this->_redirect('./');
        print_r($action);
        print_r($arguments);
    }
}
