In Symfony, you can handle file download responses using the BinaryFileResponse
class. Here's how you can create and return a file download response in a controller action:
BinaryFileResponse
with the path to the file you want to download:use Symfony\Component\HttpFoundation\BinaryFileResponse;
public function downloadAction()
{
$filePath = '/path/to/your/file.txt';
$response = new BinaryFileResponse($filePath);
return $response;
}
$response->setContentDisposition(
ResponseHeaderBag::DISPOSITION_ATTACHMENT,
'custom_filename.txt'
);
BinaryFileResponse
object from your controller action, and Symfony will handle sending the file download response to the client.return $response;
With this approach, Symfony will handle streaming the file content to the client, and the user will be prompted to download the file to their local machine.
