使用Zend \ Db連接到數據庫

Question

我試圖在我的應用程序中實現Zend Db。

目前，我正在使用會話管理器。

DB是發起這樣：

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()); 

雖然我的配置文件看起來像這樣：

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' 
    ) 
) 
); 

當我試圖執行一個選擇：

$sql = new Sql($this->database); 
$query = $sql->select(); 
$query->from('sessions'); 
$query->columns(array('sessionid')); 
$query->where(array('sessionid' => $sessionId)); 

$stmt = $sql->prepareStatementForSqlObject($query); 
$result = $stmt->execute(); 

我出現錯誤：

Connect Error: SQLSTATE[HY000] [1045] Access denied for user ''@'localhost' (using password: NO) 

很酷，這是一個連接錯誤......但連接丟失或者我應該說什麼，證書在哪裏丟失？讓我們來看看數據庫對象...

[lastPreparedStatement:protected] => 
) 

看起來像被設置連接參數 - 太棒了！但它仍然沒有連接。

在ZF 2，你不需要一個名爲params鍵：

http://framework.zend.com/manual/2.0/en/modules/zend.db.adapter.html

$adapter = new Zend\Db\Adapter\Adapter(array(
    'driver' => 'Mysqli', 
    'database' => 'database', 
    'username' => 'username', 
    'password' => 'password' 
));
