Delete file after download

I have a situation that should download and delete the file. Is there any possibility?

I'm using this function in response:

PHP Code:

return $response->download($name, $data); 


Anything like that, for example:

PHP Code:

// Other framework
return response()->download($filePath, $fileName, $headers)->deleteFileAfterSend(true); 


---

This is the bad solution?

PHP Code:

Controller:

// Set header content disposition file
header("Content-Disposition: attachment; filename=" . $fileName);

// Force download writer to output
$writer->save('php://output');

// Remove file after download
unset($filePath);

// Break request to not corrupt the file
exit(); 


Im using PHP Spreedsheet library.
