What PHP settings or headers can be adjusted to ensure proper display of special characters?

Special characters may not display properly in PHP due to incorrect character encoding settings. To ensure proper display of special characters, you can adjust the following PHP settings or headers: 1. Set the character encoding in the PHP script using `header('Content-Type: text/html; charset=UTF-8');` to specify UTF-8 encoding. 2. Make sure your PHP files are saved with UTF-8 encoding to support special characters. 3. Use htmlentities() or htmlspecialchars() functions to encode special characters before outputting them on the webpage. 

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