How can debugging techniques be used to identify the root cause of session registration problems in PHP?

Session registration problems in PHP can be identified by using debugging techniques such as printing out session variables, checking for errors in session handling functions, and verifying session configuration settings. By carefully examining the session flow and data, developers can pinpoint the root cause of registration issues and implement the necessary fixes. 

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

// Debugging session registration
echo "Session ID: " . session_id() . "<br>";
echo "Session Data: ";
print_r($_SESSION);
?>
