What are the best practices for handling data transfer between multiple pages in PHP?

When transferring data between multiple pages in PHP, it is best practice to use session variables to store and retrieve the data. This ensures that the data is available across different pages during a user's session. By using session variables, you can easily pass data between pages without the need to use GET or POST methods, which can expose sensitive information. 

// Start the session
session_start();

// Set data in session variable on one page
$_SESSION['data'] = "Hello, World!";

// Retrieve data from session variable on another page
$data = $_SESSION['data'];

// Unset the session variable when no longer needed
unset($_SESSION['data']);
