Session,cookies and get and post methods
This document provides an overview of sessions, cookies, and the GET and POST methods in HTTP. It defines sessions and cookies as ways to store user information on the server and client-side, respectively. GET sends data via the URL while POST embeds it in the request body. Examples demonstrate how to set, access, and destroy sessions and cookies in PHP, and how forms can use GET and POST to send different types of data to the server.
