How can the use of superglobal arrays improve session handling in PHP scripts?

Superglobal arrays like $_SESSION can improve session handling in PHP scripts by providing a centralized and secure way to store and retrieve session data. By using $_SESSION, developers can easily access session variables across different pages without the need to pass data through URLs or hidden form fields. This helps in maintaining session state and simplifies session management in PHP scripts. 

// Start the session
session_start();

// Store data in the session
$_SESSION['username'] = 'JohnDoe';

// Retrieve data from the session
$username = $_SESSION['username'];

// Destroy the session
session_destroy();
