我如何连接到其他服务器上的数据库，例如来自heroku上托管的pdo codeigniter项目的db4free.net

Question

我正在尝试使用db4free.net上的外部mysql数据库在heroku上托管一个codeigniter项目。

我尽力而为，但我最后的努力看起来像这样

$db['mysql'] = array(
	'dsn'	=> 'mysql:hostname="db4free.net"; dbname=ravenstock',
	'hostname' => '',
	'username' => 'ravenstockadmin',
	'password' => '**************',
	'database' => '',
	'dbdriver' => 'pdo',
	'dbprefix' => '',
	'pconnect' => FALSE,
	'db_debug' => (ENVIRONMENT !== 'production'),
	'cache_on' => FALSE,
	'cachedir' => '',
	'char_set' => 'utf8',
	'dbcollat' => 'utf8_general_ci',
	'swap_pre' => '',
	'encrypt' => FALSE,
	'compress' => FALSE,
	'stricton' => FALSE,
	'failover' => array(),
	'save_queries' => TRUE
);
