What are the potential security risks of storing customer names and profile pictures as cookies in PHP?

Storing customer names and profile pictures as cookies in PHP can pose a security risk as cookies are stored on the client-side and can be easily tampered with. To mitigate this risk, sensitive data should not be stored in cookies. Instead, you can store a unique identifier in the cookie and retrieve the corresponding data from a secure server-side storage, such as a database. 

// Set a unique identifier in the cookie
$userId = 123;
setcookie('user_id', $userId, time() + 3600, '/');

// Retrieve user data from a secure server-side storage
$userData = getUserData($userId);

function getUserData($userId) {
    // Implement logic to retrieve user data from a secure server-side storage
    return $userData;
}
