    return "文章总数：{$totalArticles}，评论总数：{$totalComments}，总浏览量：{$totalViews}";
}
echo getSiteStats();
?>

Through the above example code, we can see the importance and application of PHP in the DreamWeaver system, It is not only the core language for dynamic web pages and data processing, but also a powerful tool for extended functionality and customization. With the power of PHP, DreamWeaver System can better meet the needs of website builders and provide users with a richer and more personalized website experience.
