What are some best practices for handling headers in PHP to avoid errors like the one mentioned in the forum thread?

The issue mentioned in the forum thread is likely related to attempting to modify headers after they have already been sent to the browser, which can result in errors. To avoid this, it is best practice to ensure that any header modifications are done before any content is output to the browser.

<?php
// Correct way to set headers in PHP to avoid errors
header('Content-Type: text/html');

// Other PHP code goes here
?>
