What are some best practices for managing session cookies in PHP applications?

Session cookies in PHP applications should be managed securely to prevent unauthorized access and data breaches. Some best practices include setting secure and HttpOnly flags on session cookies, using SSL/TLS for secure communication, regenerating session IDs after successful login, and validating session data to prevent tampering. 

// Set session cookie parameters
session_set_cookie_params([
    'lifetime' => 0,
    'path' => '/',
    'domain' => 'example.com',
    'secure' => true,
    'httponly' => true
]);

// Start session
session_start();

// Regenerate session ID after successful login
session_regenerate_id(true);

// Validate session data
if(isset($_SESSION['user_id'])) {
    // User is authenticated
} else {
    // Redirect to login page
    header('Location: login.php');
    exit();
}
