Bootstrap di zend

sintak untuk bootstrap.php di zend framework versi saya adalah sebagai berikut :

<?php

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
protected function _initDoctype()
{
$this->bootstrap('view');
$view = $this->getResource('view');
$view->doctype('XHTML1_STRICT');
}

public function _initRegistry(){
// //$this->bootstrap("multidb.db1");
// $db1=$this->getResource("multidb.db1");
// $db2=$this->getResource("multidb.db2");
// Zend_Registry::set("db",$db1);
// Zend_Registry::set("db2",$db2);
}

public function _initDatabase(){
$resource = $this->getPluginResource('multidb');
$resource->init();

Zend_Registry::set('db1', $resource->getDb('db1'));
Zend_Registry::set('db2', $resource->getDb('db2'));
}

}
