Description:
As an entry-level developer, your task is to create a simple user registration system using PHP, MySQL, and JavaScript. The system should allow users to register an account, log in, and view their profile information.

Requirements:

Registration Page:

Users should be able to provide their username, email address, and password.
Validate the input fields for proper formatting (e.g., valid email address).
Store the user’s information securely in a MySQL database.
Login Page:

Users should be able to enter their username/email and password to log in.
Authenticate the login credentials against the stored data in the database.
Upon successful login, redirect the user to their profile page.
Profile Page:

Display the user’s profile information retrieved from the database.
Allow users to edit and update their profile information (username, email, password).
Implement appropriate validation and security measures for updating user information.
JavaScript Validation:

Implement client-side validation using JavaScript for the registration and login forms.
Validate required fields, email format, password strength, etc.
Provide real-time feedback to users about any input errors.
Additional Guidelines:

Use PHP to handle server-side processing, such as database interactions and form submissions.
Utilize MySQL to create a database and store user information securely.
Implement proper security measures, such as hashing passwords and preventing SQL injection.
Keep the design and user interface simple and intuitive.
Test the application thoroughly to ensure all functionalities are working as expected.
