1. The main difference between cookies and sessions is that cookies are stored on the user’s computers in the text file format, and sessions are stored on the server.
2. A Cookies can keep the information on the user’s system untill deleted whereas Session stored the information while the user has their browser open.
3. Session can hold multiple variables, whereas Cookies can not hold multiple variables.
4. Session data is stored in a cookie with an expiry date of zero, That means the session only remains active as long as the browser is open,after closing the browser, all the stored information is lost. You can modify this behavior from the php.ini file set the session.cookie_lifetime from zero to your specific value you want.
5. Sessions are stored on the server, that means clients do not have access to the information you stored about them, so that it is secure and the cookies are stored on the system so that information stored into it is not so much secure as the session values.
