Php Zend/Db不在Zend Framework 3中工作？

如何使用ZF3 db factory方法连接mysql数据库

$db = Zend_Db::factory('Pdo_Mysql', array(
      'host'      => MASTER_HOST,
      'username'  => MASTER_USER,
      'password'  => MASTER_PASSWORD,
      'dbname'    => DB_ADMIN,
      'port'      => MASTER_HOST_PORT,
      );

在ZF3（或ZF2）中，必须使用

Zend\Db\Adapter\Adapter

$config = array(
  'driver'   => 'Pdo',
  'dsn'      => 'mysql:dbname=db;host=localhost',
  'username' => 'root',
  'password' => 'root',
);
// or
$config = $serviceLocator->get('Config')['db'];

$db = new \Zend\Db\Adapter\Adapter($config);
