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).
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?
Or is there an even better way to do it?
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);
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');
...
}
