What is the best way to handle URL redirection for multiple languages in PHP?

When dealing with multiple languages in a PHP website, it's important to handle URL redirection properly to ensure users are directed to the correct language version of the site based on their preferences or location. One way to achieve this is by using a combination of language detection, URL parsing, and redirection logic in PHP code. 

// Get the current URL
$currentUrl = $_SERVER['REQUEST_URI'];

// Define an array of supported languages and their corresponding URL prefixes
$languages = array(
    'en' => '/en',
    'es' => '/es',
    'fr' => '/fr'
);

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

// Check if the user's preferred language is supported
if (array_key_exists($userLanguage, $languages)) {
    // Redirect the user to the corresponding language version of the site
    header('Location: ' . $languages[$userLanguage] . $currentUrl);
    exit;
}
