How can the HTTP_ACCEPT_LANGUAGE header be utilized in PHP for multi-language support instead of IP-based detection?

The HTTP_ACCEPT_LANGUAGE header can be utilized in PHP for multi-language support by parsing the header to determine the preferred language of the user's browser. This allows for a more accurate language selection compared to IP-based detection, which may not always reflect the user's actual language preference. 

$acceptedLanguages = $_SERVER['HTTP_ACCEPT_LANGUAGE'];
$preferredLanguage = strtok($acceptedLanguages, ',');
$preferredLanguage = strtok(';');
$preferredLanguage = strtok('-');
// Use the preferred language to set the appropriate language for the user
