How can PHP scripts be properly encoded and saved to handle UTF-8 characters, especially when directly defining HTML within the script?

PHP scripts can be properly encoded to handle UTF-8 characters by ensuring that the script itself is saved with UTF-8 encoding and that any HTML output within the script is also properly encoded using htmlentities() or htmlspecialchars() functions. This will prevent any issues with special characters breaking the HTML structure or causing encoding errors.

<?php
// Set UTF-8 encoding for the script
header('Content-Type: text/html; charset=utf-8');

// Define HTML content with UTF-8 characters properly encoded
$html = '<p>This is a UTF-8 encoded string: ' . htmlentities('é') . '</p>';

echo $html;
?>
