The purpose of creating this website was to learn how to implement PHP in web development. The website uses PHP's session storage to provide a fully functional signup and login mechanism. Users can create accounts, and their activities are saved in the session storage. When logged in, users can create notes with a title, description, and image. The website also features a car shop, demonstrating simple e-commerce functionality, including adding cars to a cart, clearing the cart, and live total price updates. Cars in the shop are represented by objects with images, prices, and descriptions to inform users about the details. Additionally, I learned how to implement lazy loading for images that take longer to load.
