我有一个使用 Zend Framework 构建的网站，由 Windows 10 上的 Wamp32 和 PHP 7 运行，连接到 MySQL 数据库。

我现在正在尝试添加到 DashDB 的连接。

我从这里下载了 PECL 文件，将它们安装在 PHP 7 的 ext 目录中，将它们添加到php.ini文件中，我可以在 WAMP 的扩展菜单中看到php_ibm_db2和php_pdo_ibm。

在我的global.php文件中，我有以下内容：

$database = "BLUDB";
$user = "dashdb_user";
$password = "dashdb_passwd";
$hostname = "dashdb_host";
$port = 50000;

return array(
    'db' => array(
        'driver'         => 'Pdo',
        'dsn'            => 'mysql:dbname=mysql_db;host=localhost',
        'driver_options' => array(
            PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
        ),
        'adapters'=>array(
            'db2' => array(
                'driver'         => 'IbmDb2',
                'database' => "DRIVER = { IBM DB2 ODBC DRIVER }; DATABASE = $database; HOSTNAME=$hostname; PORT = $port; PROTOCOL = TCPIP ; UID = $user ; PWD = $password;",
            ),
        )
    ),

我还在local.php文件中将凭据添加到 DashDB

return array(
    'db' => array(
        // for primary db adapter that called
        // by $sm->get('Zend\Db\Adapter\Adapter')
        'username' => 'mysql_username',
        'password' => mysql_passwd',

        // to allow other adapter to be called by
        // $sm->get('db1') based on the adapters config.
        'adapters' => array(
            'db2' => array(
                'username' => 'dashdb_user',
                'password' => 'dashdb_passwd',
            ),
        ),
    ),
);

最后在Module.php文件中，我有：

public function onBootstrap(MvcEvent $e)
{
    $eventManager        = $e->getApplication()->getEventManager();
    $moduleRouteListener = new ModuleRouteListener();
    $moduleRouteListener->attach($eventManager);

    $sm = $e->getApplication()->getServiceManager();
    $sm->get('db2');
}

但是当我尝试加载网站时，会出现此错误：

( ! ) Fatal error: Uncaught Zend\Db\Adapter\Exception\RuntimeException: The ibm_db2 extension is required by this driver. in F:\wamp\www\playdon_website\vendor\zendframework\zend-servicemanager\src\ServiceManager.php on line 1130
