Symfony2 - Force file download

Question

I'm trying to download a file when a user clicks on download link. In Controller: ``` $response = new Response(); $response->headers->set('Content-type', 'application/octect-stream'); $response->headers->set('Content-Disposition', sprintf('attachment; filename="%s"', $filename)); $response->headers->set('Content-Length', filesize($filename)); return $response; ``` This is opening the dialog box to save the file, but it says the file is 0 bytes. And changing it to: ``` $response = new Response(); $response->headers->set('Content-type', 'application/octect-stream'); $response->headers->set('Content-Disposition', sprintf('attachment; filename="%s"', $filename)); $response->headers->set('Content-Length', filesize($filename)); $response->headers->set('Content-Transfer-Encoding', 'binary'); $response->setContent(readfile($filename)); return $response; ``` I get a bunch of weird characters instead of the file download dialog box. Finally, switching the "setContent" line to: ``` $response->se…

Accepted Answer

I finally solved this without X-SendFile (which is probably the best practice). Anyway, for those who can't get X-Sendfile apache module to work (shared hosting), here's a solution:

```
// Generate response
$response = new Response();

// Set headers
$response->headers->set('Cache-Control', 'private');
$response->headers->set('Content-type', mime_content_type($filename));
$response->headers->set('Content-Disposition', 'attachment; filename="' . basename($filename) . '";');
$response->headers->set('Content-length', filesize($filename));

// Send headers before outputting anything
$response->sendHeaders();

$response->setContent(file_get_contents($filename));

return $response;
```
