Use header application/x-download

Question

Zend framework 1. Physically, the file does not exist, it is created based on database.

Okay so use header?

public function downloadAction()
{
 $id = $this->getRequest()->getParam("id");
 $optin = new Application_Model_Optin();
 //$data = $optin->getCodesFromDownload($id);
 $data = array(
 array('code' => 12345),
 array('code' => 12346),
 array('code' => 12347),
 array('code' => 12348),
 array('code' => 12349)
 );
 header("Content-type: application/x-download");
 header("Content-disposition: attachment; filename=code_" . $id . ".csv");
 foreach($data as $item)
 {
 echo $item['code']."\r\n";
 }
 die;
}

Answer 1

Yes. It is perfectly acceptable.

This Stack Overflow post demonstrates that the header is simply used for naming the file.
