用PHP上传文件并授予该文件的权限

Question

I need develop a web app like www.Sharefile.com. I want users to upload and then give permissions to that file for access by particular users only.

I don't know how to give permissions for server files (upload file like pdf,word) using PHP.

Answer 1

You ask a general question, so you get a general answer: I assume you already have some login set up for these users to upload their files. Using this same login system, you can control permissions on specific files. This is not necessarily done in php itself. For example, user and file permissions may be stored in a DB. The files themselves will probably have usual permissions.
