You will implement a basic registration and login system. You will get practice with forms, sending requests, and working with a MySQL database

​

Write the login form: Write a PHP file that will output a form containing 2 fields: username and password. Upon submission of the form, the code should check against the database to see whether the usernamepassword pair was correct. If so, display a welcome message. If not, display the message “Invalid username or password” followed by the same login form

 

Write the registration form:  Write a PHP file that will output a form containing 3 fields: username, password, and phone number. These fields should be sent via POST to the same file, which should take care of inserting them into a database

 

Write the reset password form: Write a form to allow a user to reset their password with their username and phone number. If the username and phone number match entries in the database, you should generate a random string as a password (make it of reasonable length, alphanumeric).

​

Write the change password form: Write a form to allow a user to change their password. It should take 3 fields: the username, current password, and new password. When the form is submitted, the code should make appropriate checks against the database, and if the username and password are correct, modify the entry to reflect the change in password. The user should receive a message that informs them of the successful password change. Remember that the database stores the hash of the password.

​

Keep me logged in: A successful login should set some session variable so that the server knows that the user is logged in
