How can PHP developers effectively troubleshoot issues with session handling in form submissions?

When troubleshooting issues with session handling in form submissions in PHP, developers should first ensure that sessions are properly started at the beginning of the script and that session variables are being set and accessed correctly. They should also check for any errors in session configuration settings or conflicts with other session-related functions. Additionally, developers can use tools like var_dump() or print_r() to inspect session variables and debug any issues. 

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

// Set session variables
$_SESSION['username'] = 'john_doe';
$_SESSION['user_id'] = 12345;

// Access session variables
echo $_SESSION['username'];
echo $_SESSION['user_id'];
?>
