What are some potential pitfalls of using cookies for session management in PHP?

One potential pitfall of using cookies for session management in PHP is that they can be easily tampered with by malicious users, leading to security vulnerabilities. To mitigate this risk, it is recommended to use server-side session management techniques, such as storing session data in server-side files or databases. 

// Use server-side session management in PHP
session_start();
// Session data can be stored and accessed using the $_SESSION superglobal
$_SESSION['user_id'] = 123;
