User Authentication in PHP

 1) Basic authentication:
     We hard code the username and password combination in the login script itself. Suitable for simple application

2) User & password stored in database:
     A very common method. We store all the user name and password information in the database

3) User authentication with image verification:
    This is a more advance method of user authentication. We can prevent any automatic login by a robot ( script ) by using this method
