yii2 Create new folder and add file to it - php

Question

I'm creating Yii2 application that allows users to download tutorial and it's subtitle. Currently I can do it separately but, what I want to do is to create a new folder with the video name and include both video and subtitle file in that folder and then create a zip and give that to the user for download. but I have no idea how to do it. I can zip the files using php ZipArchive but i have no idea how to create new folder and include those two files in to it.
my download action is
public function actionDownload($id)
{
// get all videos relevan for this video id
$video = TempVideo::findOne($id);
$file = $video->path;
if (file_exists($file))
{
Yii::$app->response->sendFile($file);
}
}
helps are highly appreciated.

Answer 1

You could use ZipArchive
http://php.net/manual/en/zip.examples.php
or launch command line with:
system('zip filecompress.zip file1 file2 file3');

Answer 2

I don't have all the information but i think it need to mlook something like this:
you need to make a new directory with mkdir() (doc: http://php.net/manual/en/function.mkdir.php);
and copy the needed files with copy()
(doc:http://php.net/manual/en/function.copy.php)
public function actionDownload($id)
{
// get all videos relevan for this video id
$video = TempVideo::findOne($id);
$file = $video->path;
if (file_exists($file))
{
Yii::$app->response->sendFile($file);
$new_video_path = '/path/to/save/dir';
//create a new dir
mkdir($new_video_path);
//copy the file to a new path
copy($file,$new_video_path.'newfilename.mp4');
copy('subtitle/pathe.txt',$new_video_path.'subtitle.txt');
}
}
and after that you can create a zip file with the ZipArchive that doc can be found here: http://php.net/manual/en/class.ziparchive.php
