What are some best practices for storing user login data in cookies in PHP?

Storing user login data in cookies in PHP can pose security risks if not done properly. To enhance security, it is recommended to encrypt the user login data before storing it in cookies. This can help prevent unauthorized access to sensitive information. 

```php
// Encrypt user login data before storing in cookies
$encryptionKey = "YourEncryptionKeyHere";
$encryptedData = openssl_encrypt($userData, 'AES-256-CBC', $encryptionKey, 0, 'YourInitializationVectorHere');

// Set the encrypted data in a cookie
setcookie('login_data', $encryptedData, time() + 3600, '/');
```

Remember to replace "YourEncryptionKeyHere" and "YourInitializationVectorHere" with your actual encryption key and initialization vector. Additionally, make sure to decrypt the data when retrieving it from the cookie for use in your application.
