Laravel - display a PDF file in storage without forcing download?

Update for 2017

As of Laravel 5.2 documented under Other response types you can now use the file helper to display a file in the user's browser.

return response()->file($pathToFile);

return response()->file($pathToFile, $headers);

You just need to send the contents of the file to the browser and tell it the content type rather than tell the browser to download it.

$filename = 'test.pdf';
$path = storage_path($filename);

return Response::make(file_get_contents($path), 200, [
    'Content-Type' => 'application/pdf',
    'Content-Disposition' => 'inline; filename="'.$filename.'"'
]);

If you use Response::download it automatically sets the Content-Disposition to attachment which causes the browser to download it. See this question for the differences between Content-Disposition inline and attachment.

Edit: As per the request in the comments, I should point out that you'd need to use Response at the beginning of your file in order to use the Facade.

use Response;

Or the fully qualified namespace if Response isn't aliased to Illuminate's Response Facade.

Since Laravel 5.2 you can use File Responses
Basically you can call it like this:

return response()->file($pathToFile);

and it will display files as PDF and images inline in the browser.
