What are some best practices for managing and displaying session data in PHP?

When managing and displaying session data in PHP, it is important to securely store sensitive information and properly sanitize and validate user input to prevent security vulnerabilities. It is recommended to use built-in PHP session functions to manage session data effectively. 

// Start the session
session_start();

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

// Display session data
echo 'User ID: ' . $_SESSION['user_id'];
echo 'Username: ' . $_SESSION['username'];
