How do I work with sessions

Working with sessions in PHP allows you to store user data across multiple pages. Sessions are particularly useful for maintaining user state and information during their interaction with web applications. Below is an example of how to start a session, set session variables, and access them.


            <?php
            // Start the session
            session_start();

            // Set session variables
            $_SESSION["username"] = "JohnDoe";
            $_SESSION["email"] = "johndoe@example.com";
            ?>

            // Access session variables
            <?php
            echo "Username: " . $_SESSION["username"] . "<br>";
            echo "Email: " . $_SESSION["email"];
            ?>
