Q:

How to create a user-based file upload storage system in PHP and MySQL? 

It will be user based; user can store file by uploading it to database/server. 
Just like little cloud, user can view files anytime after logging in. 
How can I make a start on the implementation?  I need to store files as per user account, can't plan for database implementation.
