What are the best practices for creating and maintaining sessions in PHP to ensure continuity for users?

To create and maintain sessions in PHP for user continuity, it is important to start the session at the beginning of each page, set session variables as needed, and destroy the session when the user logs out or after a certain period of inactivity. Additionally, using session_regenerate_id() to prevent session fixation attacks is recommended. 

// Start the session
session_start();

// Set session variables
$_SESSION['user_id'] = 123;
$_SESSION['username'] = 'example_user';

// Regenerate session ID to prevent session fixation attacks
session_regenerate_id();

// Destroy the session when the user logs out
session_destroy();
