How can debugging techniques be effectively used to troubleshoot session-related issues in PHP?

Session-related issues in PHP can often be caused by incorrect session configuration, expired session data, or conflicts with other session variables. To troubleshoot these issues, you can start by checking the session configuration settings in your php.ini file, ensuring that session_start() is called at the beginning of each script, and verifying that session data is being properly stored and retrieved. 

// Check session configuration settings in php.ini
echo ini_get('session.save_path');

// Ensure session_start() is called at the beginning of each script
session_start();

// Verify session data is being properly stored and retrieved
$_SESSION['test'] = 'Hello, World!';
echo $_SESSION['test'];
