What are the potential pitfalls in relying on browser language information for international platforms in PHP?

Relying solely on browser language information for international platforms in PHP can be problematic as it may not always accurately reflect the user's preferred language. To address this issue, a more reliable approach would be to allow users to manually select their preferred language from a dropdown menu or through their user profile settings. 

// Example of allowing users to manually select preferred language
$userLanguage = isset($_POST['language']) ? $_POST['language'] : '';
$availableLanguages = ['en', 'es', 'fr']; // List of available languages

if(in_array($userLanguage, $availableLanguages)) {
    // Set user's preferred language
    $_SESSION['user_language'] = $userLanguage;
} else {
    // Default to English if user's selected language is not available
    $_SESSION['user_language'] = 'en';
}
