How can understanding the order of operations in PHP code execution help in troubleshooting issues related to session management?

When troubleshooting issues related to session management in PHP, understanding the order of operations in code execution is crucial. This is because the session_start() function, which initializes a session, must be called before any output is sent to the browser. Failure to do so can result in session-related errors or unexpected behavior.

<?php
session_start();
// Other PHP code here
?>
