How can PHP developers ensure proper encoding and character set in their HTML and PHP files?

To ensure proper encoding and character set in HTML and PHP files, developers can set the charset in the HTML meta tag and also specify the encoding in PHP files using the header function. This helps to ensure that the content is displayed correctly and avoids any character encoding issues. 

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<body>

<?php
header('Content-Type: text/html; charset=UTF-8');
?>
