How can PHP sessions be utilized to store and access variables for consistent use across multiple pages on a website?

To store and access variables across multiple pages on a website using PHP sessions, you can set session variables on one page and then access them on subsequent pages. This allows you to maintain consistent data throughout the user's session on the website. 

// Start the session
session_start();

// Set a session variable
$_SESSION['username'] = 'JohnDoe';

// Access the session variable on another page
session_start();
echo 'Welcome, ' . $_SESSION['username'];
