How can PHP sessions be utilized more effectively to store and retrieve session data?

To utilize PHP sessions more effectively in storing and retrieving session data, it is recommended to use the $_SESSION superglobal array to store and access session variables. This allows for easy manipulation of session data throughout the user's session. Additionally, setting session variables with meaningful names can help organize and manage the data more efficiently. 

// Start the session
session_start();

// Store data in session variables
$_SESSION['username'] = 'JohnDoe';
$_SESSION['email'] = 'johndoe@example.com';

// Retrieve and use session data
$username = $_SESSION['username'];
$email = $_SESSION['email'];

// Display session data
echo "Welcome back, $username. Your email is $email.";
