如何在zend框架中将多张图片上传到数据库中

// 在控制器中的上传动作方法
public function uploadAction()
{
    $form = new Application\Form\UploadForm();
    $request = $this->getRequest();

    if ($request->isPost()) {
        $form->setData($request->getPost());

        if ($form->isValid()) {
            $data = $form->getData();

            // 保存上传的文件到服务器指定目录
            $uploadDir = '/path/to/upload/directory/';
            $adapter = new Zend\File\Transfer\Adapter\Http();
            $files = $adapter->getFileInfo();

            foreach ($files as $file => $info) {
                if ($adapter->isValid($file)) {
                    $adapter->setDestination($uploadDir);
                    $adapter->receive($file);

                    // 将文件信息插入数据库
                    $filename = $adapter->getFileName($file);
                    $fileType = $adapter->getMimeType($file);
                    $fileSize = $adapter->getFileSize($file);

                    $image = new Application\Model\Image();
                    $image->setFilename($filename);
                    $image->setType($fileType);
                    $image->setSize($fileSize);

                    $imageTable = $this->getServiceLocator()->get('Application\Model\ImageTable');
                    $imageTable->save($image);
                }
            }

            // 重定向到成功页面
            return $this->redirect()->toRoute('success');
        }
    }

    return array('form' => $form);
}
