When should we use session and cookies in PHP? Please specify separately their uses,pros and cons.
Well, explaining it “separately” will be difficult since cookies are mostly used to store a session identifier on the clients machine. This is done by PHP automatically as soon as you start session (can be configured differently).
The session is then used to identify and recognize the user and to pass information from one request to the next that the user must not be allowed to modify (session data is stored on the server).
Cookies can also be used to store data on the clients machine that is not security related and that can be used to remember a certain state on the page for the user for example.
Just remember: Cookies can be easily manipulated. Use Session for everything that is security related.
