In what ways can tools like Firebug and the W3C Validator be used to troubleshoot and fix encoding errors in PHP-generated HTML content?

Encoding errors in PHP-generated HTML content can be troubleshooted and fixed using tools like Firebug and the W3C Validator by identifying any inconsistencies in the character encoding specified in the HTML document and the actual encoding being used. Firebug can help inspect the response headers and content to check for encoding issues, while the W3C Validator can identify any invalid characters or encoding declarations in the HTML. Once the issue is identified, it can be fixed by ensuring that the correct encoding is specified in the PHP code or in the HTML document. 

<?php
header('Content-Type: text/html; charset=utf-8');
echo "<html>";
echo "<head>";
echo "<meta charset='utf-8'>";
echo "</head>";
echo "<body>";
echo "Your PHP-generated content here";
echo "</body>";
echo "</html>";
?>
