How does using $_SERVER['HTTP_REFERER'] differ from $_SERVER['HTTP_ACCEPT_LANGUAGE'] in PHP?

$_SERVER['HTTP_REFERER'] is used to retrieve the URL of the referring page that linked to the current page, while $_SERVER['HTTP_ACCEPT_LANGUAGE'] is used to retrieve the preferred language of the user's browser. To implement the fix, you can use $_SERVER['HTTP_ACCEPT_LANGUAGE'] to determine the user's preferred language and then redirect them to a specific page based on that language. 

$preferred_language = $_SERVER['HTTP_ACCEPT_LANGUAGE'];
if(strpos($preferred_language, 'en') === 0){
    header('Location: english_page.php');
} elseif(strpos($preferred_language, 'fr') === 0){
    header('Location: french_page.php');
} else {
    header('Location: default_page.php');
}
