What are the potential pitfalls of using cookies for long-term storage of information in PHP?

One potential pitfall of using cookies for long-term storage of information in PHP is that cookies have a limited storage capacity, so storing large amounts of data may not be feasible. Additionally, cookies are sent with every HTTP request, which can impact performance. To address these issues, consider using server-side storage solutions such as sessions or databases for storing large amounts of data or sensitive information. 

// Example of using sessions for long-term storage of information in PHP
session_start();
$_SESSION['user_id'] = 123;
$_SESSION['username'] = 'john_doe';
