推荐答案
似乎您只需要按作者对数据进行排序，但没有将它们按此顺序排列的顺序:
It seems you simply need to order your data by author, however there is no ordering that puts them in this order:
- 亨利
- 三居
- 弗雷德
- 马克
因为这不是按字母顺序升序或降序?
Because this is neither alphabetical ascending or descending?
以下查询将使您能够按作者 ASC/DESC 进行订购:
The following queries will enable you to order by author ASC/DESC:
SELECT * FROM books ORDER BY author ASC;
SELECT * FROM books ORDER BY author DESC;
但是，如果您需要以这种奇怪的顺序输出，您可能需要单独检索每个作者的书籍并一一输出:
However if you need to output in this strange order, you'll likely need to retrieve each author's books individually and output them one by one:
SELECT * FROM books WHERE author = 'Henry';
SELECT * FROM books WHERE author = 'Sanju';
SELECT * FROM books WHERE author = 'Fred';
SELECT * FROM books WHERE author = 'Mark';
然而，我不会发布如何从数据库中检索数据，因为您可以阅读在线教程以获得 PHP/MySQL 代码帮助.请参阅以下链接以获取友好的 PDO 参考:
I wont however be posting how to retrieve the data from the database, for that you can read online tutorials for PHP/MySQL code help. See the below link for a friendly PDO reference:

希望这会有所帮助 - 抱歉，我无法提供更多帮助.
Hope this helps - sorry I can't be of any more help.
