Login page Authentication: Authenticate users in a MySQL database table

This class can Authenticate users in a MySQL database table.

It can query a MySQL table to check if the password for a given user is correct.

A session is started and persistent cookies are set if the user authenticates correctly.

The class can also check if the user previously authenticated successfully by checking the user session or cookies. It can redirect to a given page depending on the result.

It can also log out the current user by removing any session or cookies.

A separate class is provided as login page controller for the PHPBasic framework.
