How can the UTF-8 encoding be properly implemented in a PHP file to display special characters correctly?

Special characters may not display correctly in PHP files if the UTF-8 encoding is not properly implemented. To ensure special characters are displayed correctly, you can set the UTF-8 encoding in the PHP file using the header() function. This tells the browser to interpret the content as UTF-8 encoded. 

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