How can PHP sessions be utilized to enhance user experience on a website?

PHP sessions can be utilized to enhance user experience on a website by storing user-specific information across multiple pages. This allows for personalized content, such as user preferences, shopping cart items, or login status, to be maintained as the user navigates through the website. 

// Start the session
session_start();

// Store user-specific information in session variables
$_SESSION['user_id'] = 123;
$_SESSION['username'] = 'example_user';

// Retrieve user-specific information from session variables
$user_id = $_SESSION['user_id'];
$username = $_SESSION['username'];

// Use the stored information to personalize the user experience
echo "Welcome back, $username!";
