What steps can be taken to troubleshoot and resolve the issue of a session not being executed in PHP code?

If a session is not being executed in PHP code, it could be due to various reasons such as session_start() not being called, session variables not being properly set or accessed, or an issue with the server configuration. To troubleshoot and resolve this issue, ensure that session_start() is called at the beginning of the script, check for any errors in setting or accessing session variables, and verify that the server is configured to support sessions. 

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

// Set a session variable
$_SESSION['username'] = 'john_doe';

// Access the session variable
echo $_SESSION['username'];
?>
