Can PHP alone handle all the necessary functionalities on a website, or is JavaScript required for specific tasks?

PHP can handle a wide range of functionalities on a website, such as server-side processing, database interactions, and dynamic content generation. However, JavaScript is often necessary for client-side interactions, such as form validation, dynamic content updates, and animations. While PHP can handle many tasks, incorporating JavaScript can enhance the user experience and provide additional functionality.
