推荐答案
在 PHP 中,您将首先使用 get_meta_tags()
获取元信息作为数组并将不同的元标记回显到任何地方希望它们显示在您的页面上.
In PHP, you would first grab the Meta information with get_meta_tags()
as an array and echo the different meta tags to wherever you want them to be displayed on your page.
例如:
$metastealer = get_meta_tags('http://yourdomain.com');
echo $metastealer['description'];
echo $metastealer['keywords'];
echo $metastealer['author'];
