How can the PHP script, server settings, and HTML structure work together to ensure consistent and correct character encoding across a web application?

To ensure consistent and correct character encoding across a web application, the PHP script should set the correct character encoding in the HTTP headers, the server settings should be configured to use the same character encoding, and the HTML structure should include a meta tag specifying the character encoding. 

<?php
// Set the character encoding in the HTTP headers
header('Content-Type: text/html; charset=UTF-8');

// Set the default character encoding for PHP
ini_set('default_charset', 'UTF-8');
?>
