How can PHP developers ensure the security of user sessions and prevent unauthorized access to sensitive data?
To ensure the security of user sessions and prevent unauthorized access to sensitive data, PHP developers can use secure session handling techniques such as using HTTPS, generating unique session IDs, regenerating session IDs after login, and storing session data securely on the server.
// Start a secure session
session_set_cookie_params(0, '/', '', true, true);
session_start();
// Regenerate session ID after successful login
session_regenerate_id(true);
// Store sensitive data securely in session variables
$_SESSION['username'] = 'example_user';
$_SESSION['is_admin'] = true;
