What role does error reporting play in troubleshooting PHP code for header modification errors?

Error reporting plays a crucial role in troubleshooting PHP code for header modification errors as it helps identify any issues related to headers already being sent before modification attempts. By enabling error reporting and fixing any output buffering or whitespace issues, developers can ensure headers are modified successfully. 

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

ob_start();

// Code to modify headers goes here

ob_end_flush();
