php - Connect to a database in Silex -


i have 

    $app->register(new silex\provider\doctrineserviceprovider(), array(     'db.options' => array(         'dbname' => 'dbname',         'user' => 'user',         'password' => '',         'host' => 'host',         'driver' => 'pdo_mysql'     ), ));

which correct, can connect database within phpstorm directly same credentials inserted in register. when 

echo '<pre>' . var_export($app['db'], true) . '</pre>';

i get:

i don't understand why it's not saying isconnected = true because credentials correct.

edit: query attempt based on silex docs example enter image description here

this results in same "whoops, looks went wrong" error.
