What best practices should be followed when working with PHP sessions, as discussed in the forum thread?

When working with PHP sessions, it is important to follow best practices to ensure security and efficiency. This includes setting a secure session cookie, regenerating the session ID regularly to prevent session fixation attacks, and properly validating and sanitizing session data to prevent injection attacks. Additionally, it is recommended to store sensitive data in server-side sessions rather than client-side cookies. 

// Set a secure session cookie
ini_set('session.cookie_secure', 1);
ini_set('session.cookie_httponly', 1);

// Regenerate session ID regularly
session_start();
if (empty($_SESSION['CREATED'])) {
    $_SESSION['CREATED'] = time();
} elseif (time() - $_SESSION['CREATED'] > 1800) {
    session_regenerate_id(true);
    $_SESSION['CREATED'] = time();
}

// Validate and sanitize session data
$_SESSION['user_id'] = filter_var($_SESSION['user_id'], FILTER_SANITIZE_NUMBER_INT);

// Store sensitive data in server-side sessions
$_SESSION['secret_data'] = encrypt($secret_data);
