// Get user input from registration form $username = $_POST['username']; $email = $_POST['email']; $password = $_POST['password']; // Create new user instance $user = new User($username, $email, $password); // Register user if ($user->register()) { echo "User registered successfully"; } else { echo "Registration failed"; }
// Get user input from login form $email = $_POST['email']; $password = $_POST['password']; // Verify user credentials $user = User::authenticate($email, $password); // Log in user if ($user) { $_SESSION['user_id'] = $user->id; echo "Logged in successfully"; } else { echo "Login failed"; }In this example, we retrieve the email and password input from the login form. We then use the `authenticate()` method to verify the user's credentials. If the user is found, we store their user ID in a session variable and display a success message. Otherwise, we display an error message. Package Library: PHP User.
