php - Symfony2: mime_content_type() not recognized -

my controller looks 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     $response->sendheaders();      $response->setcontent(readfile($filepath)); } 

passing filepath results in following error message:

call undefined function mybundle\controller\mime_content_type() 

how can solve problem?

try 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 running code. hope works fine. don't forget add

use symfony\component\httpfoundation\file\file;  

statement @ top of file.

hope helps.
