How to organize your own file storage for site users, a la cloud?

Question

PHP

There is some site. The task was to ensure that site users have a new section "My files".
This section should look like a browser for the user's directory, which is automatically created for him during registration.
The user sees his own files, can delete them, upload them, and so on.
But now I have a question: how to implement this so that he can give access to his files and folders to other users of the system by login (email)?
What can be used? Maybe there are already ready-made libraries?
Website engine in PHP.

Answer 3

Implement a script-loader that uploads a file to a temporary folder, calculates the hash, and checks the file in the database. if there is no file in the database, it saves the file to the directory you need. Well, information about the file and the hash of the file is stored in the database. Next, you just have to do the presentation of these files.
