我们尝试实现zf3教程：
https://docs.zendframework.com/tutorials/getting-started/database-and-models/
这很好用，直到我们尝试将新的indexAction（）放入RequestTable：
return new ViewModel([
'albums' => $this->table->fetchAll(),
]);`
fetchAll（）具有以下定义：
public function fetchAll()
{
return $this->tableGateway->select();
}
通过这样做，网站变白并且不会抛出任何与zendframework相关的错误。只有apache服务器显示：
PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 66719744 bytes) in Unknown on line 0
我们的module.config.php结构如下：
namespace Request;
use Request\Controller\RequestController;
use Zend\Db\Adapter\AdapterServiceFactory;
use Zend\Router\Http\Segment;
use Zend\Db\Adapter\AdapterInterface;
return [
'dependencies' => [
'factories' => [
AdapterInterface::class => AdapterServiceFactory::class,
],
],
'router' => [
'routes' => [
'request' => [
'type' => Segment::class,
'options' => [
'route' => '/request[/:action[/:id]]',
'constraints' => [
'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
'id' => '[0-9]+',
],
'defaults' => [
'controller' => RequestController::class,
'action' => 'index',
],
],
],
],
],
'view_manager' => [
'template_path_stack' => [
'album' => __DIR__ . '/../view',
],
],
];
如果我们打电话
public function fetchAll()
{
return $this->tableGateway->getTable();
}
相反，然后网站不变为白色，并且在apache中记录没有错误。没有任何事情发生。
我们的global.php应该包含与数据库相关的信息，如下所示：
return [
'db' => [
'driver' => 'pdo_mysql',
'database' => 'test_db',
'username' => 'db_tester',
'password' => 'XXXXXX',
],
];
这是我们的RequestTable.php：
namespace Request\Model;
use RuntimeException;
use Zend\Db\TableGateway\TableGatewayInterface;
class RequestTable
{
private $tableGateway;
/**
* RequestTable constructor.
* @param TableGatewayInterface $tableGateway
*/
public function __construct(TableGatewayInterface $tableGateway)
{
$this->tableGateway = $tableGateway;
}
public function fetchAll()
{
return $this->tableGateway->select();
}
这是request.php：
namespace Request\Model;
class Request{
public $request_id;
public $email;
public $type;
public function exchangeArray(array $data)
{
$this->request_id = !empty($data['request_id']) ? $data['request_id'] : null;
$this->email = !empty($data['email']) ? $data['email'] : null;
$this->type = !empty($data['type']) ? $data['type'] : null;
}
}
我们的Module.php如下所示：
namespace Request;
use Zend\Db\Adapter\AdapterInterface;
use Zend\Db\ResultSet\ResultSet;
use Zend\Db\TableGateway\TableGateway;
use Zend\ModuleManager\Feature\ConfigProviderInterface;
class Module implements ConfigProviderInterface
{
public function getConfig()
{
return include __DIR__ . '/../config/module.config.php';
}
public function getServiceConfig()
{
return [
'factories' => [
Model\RequestTable::class => function($container) {
$tableGateway = $container->get(Model\RequestTableGateway::class);
return new Model\RequestTable($tableGateway);
},
Model\RequestTableGateway::class => function ($container) {
$dbAdapter = $container->get(AdapterInterface::class);
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new Model\Request());
return new TableGateway('request', $dbAdapter, null, $resultSetPrototype);
},
],
];
}
public function getControllerConfig()
{
return [
'factories' => [
Controller\RequestController::class => function($container) {
return new Controller\RequestController(
$container->get(Model\RequestTable::class)
);
},
],
];
}
}
现在我们在添加以下内容后收到以下失败消息：
var_dump(debug_backtrace(DEBUG_BACKTRACE_IGNORE_ARGS))
错误讯息：

我们所做的只是按照上面发布的教程... 不知道这个错误信息意味着什么＆lt;。＆lt; 还在寻找任何建议!!!
