php怎么生成utf-8的html文件

php如何生成utf-8的html文件
php如何生成utf-8的html文件？？注意不是简单地加 ，而是生成文件后用记事本打开另存为后编码自动为utf-8 。

------解决方案--------------------
PHP本身是无编码的，所有的字符串通常都视为二进制流。因此只需要输入的字符串为Utf-8即可。若字符串采用其他编码，可以使用iconv系列函数转换编码。
------解决方案--------------------
fwrite ($f,"".iconv('gbk','utf-8',$html));

------解决方案--------------------

utf-8，在html文件中加入不久好了，然后给你个生成静态html的类
