How can the PHP code, HTTP headers, and HTML meta tags be used to ensure proper character encoding in a web application?

Proper character encoding in a web application can be ensured by setting the correct charset in both the HTTP headers and HTML meta tags. This helps browsers interpret the text correctly and display special characters properly. In PHP, this can be achieved by sending the appropriate charset in the HTTP headers and including a meta tag with the charset in the HTML document. 

<?php
header('Content-Type: text/html; charset=UTF-8');
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<body>
<!-- Your HTML content here -->
</body>
</html>
