特殊字符“'”没有正确显示PHP？ [关闭]

I have already ask a question related this, according to one answer I use <meta charset=utf-8>, after using this, the other special-characters are displaying properly but " ' " is not displaying properly yet.

You have to make sure that you use UTF-8 everywhere that PHP is configure to handle UTF-8.

In the html, add the meta-tag:

<meta charset="utf-8" />

And save it in UTF-8 format. here is how to do that in notepad++.

Enable UTF-8 in the php.ini:

default_charset = "utf-8"
