What suggestions were given regarding changing the database design for better handling of room bookings in PHP?

The suggestion was to create a separate table for room bookings that includes the necessary information such as room ID, booking start and end dates, and guest information. This will help in better organizing and managing room bookings in the database.

// Create a new table for room bookings
CREATE TABLE room_bookings (
    id INT AUTO_INCREMENT PRIMARY KEY,
    room_id INT,
    start_date DATE,
    end_date DATE,
    guest_name VARCHAR(50),
    guest_email VARCHAR(50)
);

// Insert a new room booking
INSERT INTO room_bookings (room_id, start_date, end_date, guest_name, guest_email) 
VALUES (1, '2022-01-01', '2022-01-05', 'John Doe', 'johndoe@example.com');
