In what scenarios would using a session be a better option for passing data between PHP scripts compared to other methods?

Using a session to pass data between PHP scripts is a better option when you need to persist data across multiple pages or when you need to securely store sensitive information. Sessions allow you to store data on the server side and access it across different pages without exposing it in the URL or form submissions. This can be especially useful for storing user authentication information or shopping cart data. 

// Start the session
session_start();

// Set data in session
$_SESSION['username'] = 'john_doe';

// Access data in another script
session_start();
echo $_SESSION['username'];
