我已经开发了一个项目，并成功地在我的本地机器上工作。在实时网站我在public_html中创建一个文件夹dev并从本地机器移动相同的项目，但它给了我以下错误。
的Zend \的ServiceManager \异常\ ServiceNotCreatedException
File: /home/projectname/public_html/dev/vendor/zendframework/zendframework/library/Zend/ServiceManager/ServiceManager.php:859
Message: An exception was raised while creating "Front/Model/Slider"; no instance returned

的Zend \ DB \适配器\异常\ RuntimeException的

Message: The PDO extension is required for this adapter but the extension is not loaded..
我的服务工厂意味着model.config.php文件是：
<?php
namespace Front;
/*use Zend\ModuleManager\ModuleManager;*/
class Module
{
public function getAutoloaderConfig()
{
return array('Zend\Loader\StandardAutoloader' =>
array('namespaces' =>
array(__NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,),
),
);
}
/* public function init(ModuleManager $moduleManager)
{
$sharedEvents = $moduleManager->getEventManager()->getSharedManager();
$sharedEvents->attach(__NAMESPACE__, 'dispatch', function($e) {
// This event will only be fired when an ActionController under the MyModule namespace is dispatched.
$controller = $e->getTarget();
$controller->layout('layout/frontlayout');
}, 100);
}
*/
public function getConfig()
{
return include __DIR__ . '/config/module.config.php';
}
// Add this method:
public function getServiceConfig()
{
return array(
'factories' => array(
'Front\Model\Cms' => function($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$table = new \Front\Model\Cms($dbAdapter);
return $table;
},
'Front\Model\Slider' => function($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$table = new \Front\Model\Slider($dbAdapter);
return $table;
},
),
);
}
}
?>
Stack Trace是这样的：

答案 0 :(得分：2)
此适配器需要PDO扩展名，但未加载扩展名
这给你答案：php有一个名为php data objects或pdo的模块。这是现代php安装中可用的模块，可以为您的php应用程序启用数据库访问。
我认为有三个可能的原因：
因此，您可能需要升级或配置服务器才能实现此功能。
