I would like to set up a website using PHP and MySQL where employers could log on securely and keep records of details pertaining to their employees.
I am experienced in the basic methods of using php to pull data out of a MySQL database. What I can't seem to find is a comprehensive article on how to set something up where a person logs in and from that point on they can only see information that belongs to them.
Furthermore, how can I get their username/password and keep it secure in addition to keeping the details of their own employees secure from others?
Tips as to where to start, what to read, URL's or whatever would be greatly appreciated. Thanks
