Use a "DB session handler" or save a time() on the user table every refresh,
when loggin verify this "time()".

Assunto: [PHP] Login should not allow users to login if the application is
logged in with the same login credentials


I've written a simple application, where users need to login to access the
features of the application. I want to develop login system such that, if
user is already logged in, the application should not allow the users to
login with the same login credentials. How do I accomplish this?
