How does php generate UTF-8 html files ?? Note that not simply adding , But after the file is generated, use notepad to open and save the file, and the encoding is UTF-8 automatically.

------ Solution --------------------
PHP itself is unencoded, and all strings are generally considered as binary streams. Therefore, you only need to enter a string for the Utf-8. If the string adopts other encoding, you can use the iconv series function to convert the encoding.
------ Solution --------------------
Fwrite ($ f, "\ xEF \ xBB \ xBF". iconv ('gbk', 'utf-8', $ html ));

Fwrite ($ f, "\ xEF \ xBB \ xBF". iconv ('gbk', 'utf-8', $ html ));

------ Solution --------------------
UTF-8, which is added to the html file Soon, I will give you a class that generates static html.
