PHP login monitor(repost)

We need a php function that stores the last date/time a user has logged in and prevents password guessing attacks

The function signature is

check_password(user's ip address, username, password)

The function

1. Does not allow the same ip address to be used for more than 100 different usernames in any given hour.

2. Does not allow a user to have more than 4 wrong (but different) passwords in 1 minute

3. Does not allow the same username to be associated with 10 different ip addresses in 5 minutes.

4. Does not allow concurrent login requests for the same user

5. Does not allow concurrent login requests for the same ip address

6. Returns a list of failed loggin attempts since last login

7. Returns the last successful login and ip address

8. Returns whether subsequent attempts will be delayed.

9. Redirects the user to the same page (with a delay reload).

The protections listed above are achieved by just asking the user to wait by 1 minute after 3 wrong passwords and 2 minutes after 10 different passwords, i.,e., protection is *not* acheived by returning a failure. If the user attempts to login when he/she should have waited, the function should fail even if the password was correct.

Use sqlite (PDO) to store relevant information.

Always salt the passwords with a random value before storing (if you dont understand what "salting" means, this project is not for you).

Two simple test scripts need to be prepared

1. Interactive demo

2. Regression testing (current requests should be made to demonstrate the correct functioning of the scripts).

1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
