How can beginners effectively troubleshoot and debug PHP scripts that involve session management and cookie handling?

To troubleshoot and debug PHP scripts involving session management and cookie handling, beginners can start by checking if sessions are being started correctly, ensuring proper session variables are being set and accessed, and verifying that cookies are being set and read accurately. Using functions like session_start(), $_SESSION[], setcookie(), and $_COOKIE[] can help in managing sessions and cookies effectively. 

<?php
// Start the session
session_start();

// Set session variables
$_SESSION['user'] = 'JohnDoe';

// Access session variables
echo $_SESSION['user'];

// Set a cookie
setcookie('username', 'JaneDoe', time() + 3600, '/');

// Read cookie value
echo $_COOKIE['username'];
?>
