How can PHP files be saved as UTF-8 to ensure proper encoding for special characters?

PHP files can be saved as UTF-8 to ensure proper encoding for special characters by specifying the UTF-8 encoding in the file header using the PHP function header('Content-Type: text/html; charset=utf-8');. This will ensure that the PHP file is saved and interpreted correctly with UTF-8 encoding. 

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