Are there any best practices to ensure the proper passing of session data in PHP scripts?

When passing session data in PHP scripts, it is important to properly sanitize and validate the data to prevent security vulnerabilities such as session hijacking or injection attacks. One best practice is to use PHP's built-in session functions to securely store and retrieve session data. 

// Start the session
session_start();

// Set session data
$_SESSION['user_id'] = 123;
$_SESSION['username'] = 'john_doe';

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

// Destroy the session when no longer needed
session_destroy();
