我正在尝试在我的应用程序中实现 Zend Db。
目前，我正在使用会话管理器。
Db 是这样启动的：
use Zend\Config\Config;
$config = new Zend\Config\Config(include ROOT . DS . 'config' . DS . 'config.php');
$database = new Zend\Db\Adapter\Adapter($config->database->toArray());
虽然我的配置文件如下所示：
return array(
'sie_product_name' => 'product name',
'salt' => 'salt',
'max_session_time' => '3600',
'database' => array(
'driver' => 'MYSQLI',
'params' => array(
'host' => 'localhost',
'username' => 'username',
'password' => 'password',
'dbname' => 'dbname'
)
)
);
我正在尝试执行选择的地方：
$sql = new Sql($this->database);
$query = $sql->select();
$query->from('sessions');
$query->columns(array('sessionid'));
$query->where(array('sessionid' => $sessionId));
$stmt = $sql->prepareStatementForSqlObject($query);
$result = $stmt->execute();
我收到错误：
Connect Error: SQLSTATE[HY000] [1045] Access denied for user ''@'localhost' (using password: NO)
酷，这是一个连接错误......但是连接在哪里丢失，或者我应该说，凭据在哪里丢失？让我们看看数据库对象...

看起来正在设置连接参数 - 太棒了！但它仍然没有连接。
