What are some potential security risks associated with storing user information in cookies in PHP?

Storing user information in cookies in PHP can pose security risks such as exposing sensitive data to potential attacks if the cookies are not properly secured. To mitigate these risks, it's important to encrypt the data stored in cookies and set appropriate security measures to prevent unauthorized access. 

// Encrypt user information before storing in a cookie
$encryptedData = openssl_encrypt($userData, 'AES-256-CBC', 'secret_key', 0, '16charIV');

// Set the cookie with the encrypted data
setcookie('user_data', $encryptedData, time() + 3600, '/', '', true, true);
