What is session and Cokkies . How it works .
tell some thing about Session_id()
Answer / Charu
Session and cookies are mechanisms used in web development to manage user sessions between multiple requests. A session stores information about a user's activity on the server side, while a cookie stores small pieces of data (like user preferences or login credentials) on the client-side browser. Session_id() is a PHP function that returns the unique identifier for the current user session. This ID is used to associate subsequent requests with the same session, allowing information to be maintained between multiple pages without needing to pass it in every request.
