使用PHP和XML来实现网站的多语言支持

    Welcome to our website!
    Hi
    Bye
    ...

function loadLanguage($language) {
    $translations = [];
    $xml = simplexml_load_file("lang.xml");
    
    foreach ($xml->translation as $translation) {
        $key = (string) $translation['key'];
        $value = (string) $translation;
        
        $translations[$key] = $value;
    }
    
    return $translations;
}

// 加载中文翻译
$chineseTranslations = loadLanguage('chinese');

// 加载英文翻译
$englishTranslations = loadLanguage('english');

// 输出欢迎消息
echo $chineseTranslations['welcome_message']; // 输出："欢迎访问我们的网站！"
echo $englishTranslations['welcome_message']; // 输出："Welcome to our website!"

// 输出问候语
echo $chineseTranslations['hi'] . "，小明"; // 输出："你好，小明"
echo $englishTranslations['hi'] . ", John"; // 输出："Hi, John"

// 输出告别语
echo $chineseTranslations['bye']; // 输出："再见"
echo $englishTranslations['bye']; // 输出："Bye"
