Are there any best practices for handling XML vs HTML responses in PHP AJAX requests?

When handling XML vs HTML responses in PHP AJAX requests, it is important to set the appropriate content type headers in the PHP script to ensure that the response is correctly interpreted by the client-side JavaScript. For XML responses, the content type should be set to "application/xml" or "text/xml", while for HTML responses, the content type should be set to "text/html". 

if ($isXmlResponse) {
    header('Content-Type: application/xml');
    echo $xmlResponse;
} else {
    header('Content-Type: text/html');
    echo $htmlResponse;
}
