PHP Login System

This is a PHP-based login system that enables users to register, log in, and log out securely. It's built with PHP for server-side scripting, HTML for structure, CSS for styling, and MySQL for the database.

Features

• User Registration: New users can create accounts with unique usernames and strong passwords.
• User Login: Registered users can securely log in to their accounts.
• Logout Functionality: Users can securely log out of their accounts.
• Data Validation:
  • Username Validation: Ensures usernames are unique and meet specified criteria.
  • Password Validation: Enforces password strength requirements.
  • Input Sanitization: Protects against SQL injection and other forms of malicious input.
