Answer 1

if you are serving a static file, you can use a BinaryFileResponse:

use Symfony\Component\HttpFoundation\BinaryFileResponse;

$file = 'path/to/file.txt';
$response = new BinaryFileResponse($file);

return $response;

More info about Serving Files in Symfony2 in the doc.

Hope this help

Are you sure, it's a good idea to share image through php?

You can write some rules for folder web/image/workflow in your server (nginx or apache).

Share them through php is bad idea. Nginx/apache can do it very fast, not using RAM (php read full image in RAM). Also, nginx/apache can cache this image.
