You can always get a reference to the front controller:
您始终可以获得对前端控制器的引用：
$front = Zend_Controller_Front::getInstance();
From that you can get the bootstrap:
从中你可以得到引导程序：
$bootstrap = $front->getParam("bootstrap");
From the bootstrap you can get bootstrap plugins:
从引导程序中，您可以获得引导程序插件：
if ($bootstrap->hasPluginResource("database")) {
$dbResource = $bootstrap->getPluginResource("database");
}
$db = $dbResource->getDatabase();
But that's a lot of extra plumbing!
但这是很多额外的管道！
Honestly, you'd be better off storing the database adapter object in the registry during your bootstrap:
老实说，最好在引导过程中将数据库适配器对象存储在注册表中：
protected function _initDatabase()
{
$params = array(
'host' => '',
'username' => '',
'password' => '',
'dbname' => '',
);
$database = Zend_Db::factory('PDO_MYSQL', $params);
$database->getConnection();
Zend_Registry::set("database", $database);
return $database;
}
Then you can get the database adapter anywhere:
然后你可以在任何地方获取数据库适配器：
Zend_Registry::get("database");

Too bad there's nothing like Zend_Controller_Action's getInvokeArg("bootstrap")in a plugin. You could always get the bootstrap reference through the front controller:
太糟糕了，插件中没有像Zend_Controller_Action'这样的东西getInvokeArg("bootstrap")。您始终可以通过前端控制器获取引导程序参考：
$db = Zend_Controller_Front::getInstance()->getParam("bootstrap")->getResource("database");
But what I usually do is
但我通常做的是
Zend_Registry::set('database', $database);
and then in your plugin:
然后在你的插件中：
try
{
$db = Zend_Registry::get('database');
}
catch (Zend_Exception $e)
{
// do stuff
}
Easier, and database can be retrieved pretty much anywhere in the application.
更容易，并且几乎可以在应用程序的任何位置检索数据库。

$db = Zend_Controller_Front::getInstance()->getParam('bootstrap')->getResource('db');

$db = Zend_Db_Table::getDefaultAdapter();
$db = Zend_Db_Table::getDefaultAdapter();
