问题描述
我正在创建一个文件保存在本地用户的计算机上（不在网络浏览器中呈现）。
I am creating a file that is to be saved on a local user's computer (not rendered in a web browser).
我目前使用 html_entity_decode ，但这不会转换像&＃8211; （这是n-dash）的字符，函数我应该使用。
I am currently using html_entity_decode, but this isn't converting characters like – (which is the n-dash) and was wondering what other function I should be using.
例如，当文件导入到软件，而不是ndash或只是一个 - 它显示为&＃8211; 。我知道我可以使用 str_replace ，但如果它发生在这个字符，它可能发生与许多其他，因为数据是动态的。
For example, when the file is imported into the software, instead of the ndash or just a - it shows up as –. I know I could use str_replace, but if it's happening with this character, it could happen with many others since the data is dynamic.
推荐答案
您需要定义目标字符集。 &＃8211; 不是默认ISO-8859-1字符集中的有效字符，因此不会解码。定义UTF-8作为输出字符集，它将解码：
You need to define the target character set. – is not a valid character in the default ISO-8859-1 character set, so it's not decoded. Define UTF-8 as the output charset and it will decode:
echo html_entity_decode('–', ENT_NOQUOTES, 'UTF-8');
如果可能，您应避免使用HTML实体。我不知道编码数据来自哪里，但如果你像这样存储在数据库或其他地方，你做错了。始终存储UTF-8编码的数据，并且只转换为HTML实体或在必要时转义以输出。
If at all possible, you should avoid HTML entities to begin with. I don't know where that encoded data comes from, but if you're storing it like this in the database or elsewhere, you're doing it wrong. Always store data UTF-8 encoded and only convert to HTML entities or otherwise escape for output when necessary.
