How can one troubleshoot and debug session management issues in PHP?

Session management issues in PHP can be troubleshooted and debugged by checking if the session is started properly, ensuring session variables are being set and retrieved correctly, and verifying that session data is being stored and maintained across page loads. One common issue is forgetting to call session_start() at the beginning of each PHP script that needs to work with session variables. 

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

// Set session variables
$_SESSION['username'] = 'john_doe';
$_SESSION['email'] = 'john.doe@example.com';

// Retrieve session variables
$username = $_SESSION['username'];
$email = $_SESSION['email'];

// Display session variables
echo "Username: " . $username . "<br>";
echo "Email: " . $email;
?>
