A bundle is only in the context of symfony needed, it wraps the orm into symfony infrastructure (services, etc.). For pure use of the orm you should read the ORM: Installation and Configuration. As you see you must create an entity manager by yourself with EntityManager::create($dbParams, $config)
, so simply create different entity managers for your different databases.
For DBAL use you should read DBAL: Configuration and see, a connection can simply obtained trough DriverManager::getConnection($connectionParams, $config);
But if you are sure the ConnectionFactory
has no dependency to symfony stuff and you really need it, you can try copy it to your code and construct a new factory to obtain a DBAL connection.
$connectionFactory = new ConnectionFactory(array());
$connection = $connectionFactory->createConnection(array(
'driver' => 'pdo_mysql',
'user' => 'foo_user',
'password' => 'foo_pass',
'host' => 'foo_host',
'dbname' => 'foo_db',
));
But take care, this is a DBAL connection, i.e. it's a abstraction layer which sits on top of PDO and only for pure SQL queries. If you need a entity manager you have to initialize it as mentioned in the docs above, or maybe you find another entity manager factory class, which you can "copy".
