I'm generating a pdf using Knp\Snappy\Pdf in my Silex application. the file name is random and saved to the tmp directory.
$filename = "/tmp/$random.pdf" $snappy->generate('/tmp/body.html', $filename, array(), true);
I think return the pdf in the response,
$response = new Response(file_get_contents($filename)); $response->headers->set('Pragma', 'public'); $response->headers->set('Content-Type', 'application/pdf'); return $response;
The pdf is displayed in the web browser correctly. The file with the random filename still exists when the request is finished. I can't unlink the file before returning the response. I've tried registering a shutdown function with register_shutdown_function and unlinking the file from there. However that doesn't seem to work. Any ideas?
