Output file structure, with the ability to navigate on the client?

Question

PHP

php gives json structures in the folder (folder-> content, folder-> content)
content - or subfolders, or pictures, links to which are needed on the client.
on the client, you need to see the folders, the ability to go into them and see the contents.
whether there is something ready for simplification, or most better.
Thank you.
