What are some common pitfalls when managing sessions in PHP?

One common pitfall when managing sessions in PHP is not properly securing session data, which can lead to security vulnerabilities. To solve this, always use HTTPS to encrypt data transmitted during the session and avoid storing sensitive information in the session itself.

// Set session cookie to be secure and HTTP only
ini_set('session.cookie_secure', 1);
ini_set('session.cookie_httponly', 1);

// Start secure session
session_start();
