Answer 1

要连接到数据库，请使用：

$dbAdapter = Zend_Db::factory('Pdo_Mysql', array(
     'host'     => '127.0.0.1',
     'username' => 'webuser',
     'password' => 'xxxxxxxx',
     'dbname'   => 'test'
));

并设置默认适配器：

Zend_Db_Table::setDefaultAdapter($dbAdapter);

有一些方法可以将特定适配器设置到表中，而无需配置默认适配器等......

您可以在文档中查看更多详细信息...请阅读它：D

在应用程序文件夹内的引导文件中添加以下代码：

protected function _initDB() {

       $dbConfig = new Zend_Config_Ini(APPLICATION_PATH . '/configs/db.ini');
       $dbAdapter = Zend_Db::factory($dbConfig->adapter, array(
            'host'     => $dbConfig->hostname,
            'username' => $dbConfig->username,
            'password' => $dbConfig->password,
            'dbname'   => $dbConfig->dbname
        ));

        My_Db_Table_Abstract::setDefaultAdapter($dbAdapter);

        Zend_Registry::set('db', $dbAdapter);


        if (APPLICATION_ENV == 'development') {
            $profiler = new Zend_Db_Profiler_Firebug('All DB Queries');
            $profiler->setEnabled(true);
            $dbAdapter->setProfiler($profiler);
        }
    }


      public function _initRouter()
        {
            $front = Zend_Controller_Front::getInstance();
            $router = $front->getRouter();

        }

} 

以及 application.ini 文件中的以下代码：

resources.db.adapter = mysqli
resources.db.params.host = localhost
resources.db.params.username = username of mysql(default root)
resources.db.params.password = password of mysql(default blank means '')
resources.db.params.dbname = test

这是没有配置数据库的问题

Answer 3

Felipe 是正确的，而教程要求在 application.ini 文件中进行此设置。

resources.db.adapter = mysqli
resources.db.params.host = localhost
resources.db.params.username = user
resources.db.params.password = pw
resources.db.params.dbname = test
