How can the use of $_SESSION variables improve the process of passing values between PHP pages?

Using $_SESSION variables can improve the process of passing values between PHP pages by storing the values on the server side and making them accessible across different pages for the same user session. This eliminates the need to pass values through URLs or forms, providing a more secure and efficient way to share data between pages. 

// Start the session
session_start();

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

// Access the session variable on another page
session_start();
echo $_SESSION['username']; // Output: JohnDoe
