How to convert HTML entities like – to their character equivalents?
提问by Cofey
I am creating a file that is to be saved on a local user's computer (not rendered in a web browser).
我正在创建一个要保存在本地用户计算机上的文件（不在 Web 浏览器中呈现）。
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.
我目前正在使用html_entity_decode，但这并没有转换像–（这是 n 破折号）这样的字符，并且想知道我应该使用什么其他功能。
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.
例如，当文件被导入软件时，而不是 ndash 或只是一个 - 它显示为–. 我知道我可以使用str_replace，但如果它发生在这个角色身上，那么它可能发生在许多其他角色身上，因为数据是动态的。

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:
您需要定义目标字符集。–不是默认 ISO-8859-1 字符集中的有效字符，因此不会对其进行解码。将 UTF-8 定义为输出字符集，它将解码：
echo html_entity_decode('–', ENT_NOQUOTES, 'UTF-8');
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.
如果可能，您应该避免使用 HTML 实体。我不知道编码数据来自哪里，但是如果您像这样将其存储在数据库或其他地方，那么您就做错了。始终存储 UTF-8 编码的数据，并且仅在必要时转换为 HTML 实体或以其他方式转义以进行输出。

Try mb_convert_encoding():
尝试mb_convert_encoding()：
$string = "n–dash";
$output = mb_convert_encoding($string, 'UTF-8', 'HTML-ENTITIES');
echo $output;

UPDATE
更新
function decode_characters($data)
{
$text = $data;
$enc = mb_detect_encoding($text, "UTF-8,ISO-8859-1");
$resutl_characters = iconv($enc, "UTF-8", $text);
return $resutl_characters;
}

Encode the file as UTF-8 using utf8_encode(). Then you don't have to replace/remove anything.
使用 .UTF-8 将文件编码为 UTF-8 utf8_encode()。然后你不必更换/删除任何东西。

Are you trying to turn the characters into HTML Entities for storage and later retrieval?
您是否试图将字符转换为 HTML 实体以供存储和以后检索？
htmlentities('–', ENT_COMPAT, 'UTF-8');
// Returns "–"
