問題描述

我這里有一個完全用 Zend FW 編寫的中型 Intranet 站點.Intranet 的數(shù)據(jù)庫位于另一臺服務(wù)器上.現(xiàn)在我需要使用一些新功能來擴(kuò)展 Intranet.為了做到這一點，我需要連接到同一臺服務(wù)器(和同一個 DBMS)上的另一個數(shù)據(jù)庫.

I have here a medium sized intranet site which is written entirely in Zend FW. The database for the intranet is located on another server. Now I need to extend the intranet with some new functionality. In order to do this I need to connect to another database on the same server (and same DBMS).

現(xiàn)在的問題是:這樣做的最佳方法是什么?我應(yīng)該創(chuàng)建一個新的 Zend_Config 對象和一個新的 Zend_Db_Adapter 嗎?或者我應(yīng)該使用現(xiàn)有的并嘗試使用use otherdbname;"在同一會話中連接到新數(shù)據(jù)庫的語句?

The question is now: What is the best way to do this? Should I create a new Zend_Config object and a new Zend_Db_Adapter? Or should I use the existing one and try with the "use otherdbname;" statement to connect within the same session to the new database?

或者有更好的方法嗎?

一種選擇是從您的 bootstrap.php 中注冊 2 個數(shù)據(jù)庫句柄，每個連接一個.例如:

One option is to register 2 database handles from within your bootstrap.php, one for each connection. E.g.:

$parameters = array(
                    'host'     => 'xx.xxx.xxx.xxx',
                    'username' => 'test',
                    'password' => 'test',
                    'dbname'   => 'test'
                   );
try {
    $db = Zend_Db::factory('Pdo_Mysql', $parameters);
    $db->getConnection();
} catch (Zend_Db_Adapter_Exception $e) {
    echo $e->getMessage();
    die('Could not connect to database.');
} catch (Zend_Exception $e) {
    echo $e->getMessage();
    die('Could not connect to database.');
}
Zend_Registry::set('db', $db);

$parameters = array(
                    'host'     => 'xx.xxx.xxx.xxx',
                    'username' => 'test',
                    'password' => 'test',
                    'dbname'   => 'test'
                   );
try {
    $db = Zend_Db::factory('Pdo_Mysql', $parameters);
    $db->getConnection();
} catch (Zend_Db_Adapter_Exception $e) {
    echo $e->getMessage();
    die('Could not connect to database.');
} catch (Zend_Exception $e) {
    echo $e->getMessage();
    die('Could not connect to database.');
}
Zend_Registry::set('db2', $db);

在您的控制器中(例如):

In your controllers (e.g.):

public function init()
{
     $this->db = Zend_Registry::get('db');
     $this->db2 = Zend_Registry::get('db2');
}

public function fooAction()
{
    $data = $this->db2->fetchAll('select foo from blah');
    ...
}
