What alternative methods can be used to effectively parse and evaluate the HTTP_ACCEPT_LANGUAGE header for language detection in PHP?

When parsing and evaluating the HTTP_ACCEPT_LANGUAGE header for language detection in PHP, one alternative method is to use the `Locale` class provided by PHP. This class allows you to parse the header and extract the language preferences in a standardized way. Another method is to use the `AcceptLanguage` library, which provides a more robust and flexible solution for parsing and evaluating language preferences. 

// Using the Locale class provided by PHP
$acceptLanguage = $_SERVER['HTTP_ACCEPT_LANGUAGE'];
$preferredLanguages = Locale::acceptFromHttp($acceptLanguage);

// Using the AcceptLanguage library
$acceptLanguage = $_SERVER['HTTP_ACCEPT_LANGUAGE'];
$parser = new \Negotiation\LanguageNegotiator();
$preferredLanguages = $parser->getBest($acceptLanguage);
