Create Zip from multiple files from folder and download from Rackspace in laravel

I am using Rackspace for storing all documents. It is storing like container_name/foldername/subfolder. All files are going to upload on sub folders. Folders and Subfolders can be multiple.

Now for e.g : i want to download all files which are in subfolder1(container_name/foldername/subfolder1). So how can i create zip file of subfolder1 and download in my local system.

Yes i can successfully create zip file and download successfully if subfolder1 is in my local system. But i can not create zip and download when i try in Rackspace.

I am using laravel version 5.4. Can anyone help me for this. It is difficult to place code here.
