How can global variables in Apache be leveraged to determine the user's location and browser settings for language redirection on a PHP website?

To determine the user's location and browser settings for language redirection on a PHP website, global variables in Apache can be leveraged by accessing the $_SERVER superglobal array. The $_SERVER['HTTP_ACCEPT_LANGUAGE'] variable can be used to retrieve the user's preferred language settings, while the $_SERVER['REMOTE_ADDR'] variable can be used to determine the user's location based on their IP address. 

// Get user's preferred language settings
$userLanguage = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);

// Get user's location based on IP address
$userLocation = $_SERVER['REMOTE_ADDR'];

// Perform language redirection based on user's language and location
if($userLanguage == 'en' && $userLocation == 'US') {
    header('Location: /en-us');
} elseif($userLanguage == 'fr' && $userLocation == 'FR') {
    header('Location: /fr-fr');
} else {
    header('Location: /default-language');
}
