Symfony2:mime_content_type()无法识别

My controller looks like this:

public function download($filepath)
{
    // Generate response
    $response = new Response();

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

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

    $response->setContent(readfile($filepath));
}

Passing a filepath to it results in the following error message:

Call to undefined function MyBundle\Controller\mime_content_type()

How can I solve this problem?

    Try to use File Class

    $oFile = new File($filepath);
    $response->headers->set('Cache-Control', 'private');
    $response->headers->set('Content-type', $oFile->getMimeType());
    $response->headers->set('Content-Disposition', 'attachment; filepath="' . $oFile->getBasename() . '";');
    $response->headers->set('Content-length', $oFile->getSize());
    

    I have not tested by running code. Hope this works fine. don't forget to add

    use Symfony\Component\HttpFoundation\File\File; 
    

    statement at the top of your file.

    Hope this helps.
