Doctrine using MySQL

I'm looking at some example documentation for Doctrine, and in the example they use SQLite. How would I get it so that it uses MySQL, with host, database, username, and password set?

In the example they use the following code:

// Database connection information
$connectionOptions = array(
    ‘driver’ => 开发者_StackOverflow‘pdo_sqlite’,
    ‘path’ => ‘database.sqlite’
);

$em – EntityManager::create($connectionOptions, $config);

AFAIK Doctrine is using DBAL object as connection in EntityManager. So that should give you an answer.
