Are there any best practices or libraries available in PHP for handling language preferences from browsers?

When a user visits a website, their browser sends a list of preferred languages in the HTTP Accept-Language header. To handle language preferences in PHP, you can parse this header and determine the most suitable language for the user based on their preferences. One common approach is to use the `Locale` class in PHP to match the preferred languages with the available languages on the website and set the appropriate language for the user. 

// Get the Accept-Language header from the browser
$acceptLanguage = $_SERVER['HTTP_ACCEPT_LANGUAGE'];

// Parse the header to extract the preferred languages
$preferredLanguages = Locale::acceptFromHttp($acceptLanguage);

// Match the preferred languages with available languages on the website
$availableLanguages = ['en_US', 'fr_FR', 'es_ES']; // Example list of available languages
$matchedLanguage = Locale::lookup($availableLanguages, $preferredLanguages, true, 'en_US');

// Set the matched language for the user
setlocale(LC_ALL, $matchedLanguage);
