How to write csv file and download in browser?

In laravel 5.7 app I need to write csv file and download in in browsers download function using method :

\Response::download(

I try to upload it to tmp directory and checking value I see

$sys_get_temp_dir= sys_get_temp_dir(); 

line above has /tmp value

Next I save it as :

$dest_csv_file= $sys_get_temp_dir . '/box_rooms_'.time().'.csv'; $header = ["Id",... ]; $fp = fopen($dest_csv_file, "w"); fputcsv($fp, $header); foreach ($storageSpacesCollection as $line) { fputcsv($fp, $line); } fclose($fp); 

But searching on my local ubuntu 18(on server I also have ubuntu) I found generated file as

/tmp/systemd-private-6a9ea6844b9c4c94883d23e4fb3e2215-apache2.service-shqCeo/tmp/box_rooms_1576324869.csv 

That was very strange, as I do not know how read it from tmp path. Can it be done?
