htmlentities and é (e acute)
提问by Michael Irigoyen
I'm having a problem with PHP's htmlentitiesand the é character. I know it's some sort of encoding issue I'm just overlooking, so hopefully someone can see what I'm doing wrong.
我遇到了 PHPhtmlentities和 é 字符的问题。我知道这是我忽略的某种编码问题，所以希望有人能看到我做错了什么。
Running a straight htmlentities("é")does not return the correct code as expected (either éor é. I've tried forced the charset to be 'UTF-8' (using the charset parameter of htmlentities) but the same thing.
直接运行htmlentities("é")不会按预期返回正确的代码（é或者é。我已经尝试将字符集强制为“UTF-8”（使用 htmlentities 的字符集参数）但同样的事情。
The ultimate goal is to have this character sent in an HTML email encoded in 'ISO-8859-1'. When I try to force it into that encoding, same issue. In the source of the email, you see é, and in the HTML view ??.
最终目标是将此字符发送到以“ISO-8859-1”编码的 HTML 电子邮件中。当我尝试强制它进入该编码时，同样的问题。在电子邮件的源代码中，您会看到 é，并在 HTML 视图中看到??。
Who can shed some light on my mistake?
谁能解释一下我的错误？

// I assume that your page is utf-8 encoded
header("Content-type: text/html;charset=UTF-8");
$in_utf8encoded = "é à ù è ò";
// first you need the convert the string to the charset you want...
$in_iso8859encoded = iconv("UTF-8", "ISO-8859-1", $in_utf8encoded);
// ...in order to make htmlentities work with the same charset
$out_iso8859= htmlentities($in_iso8859encoded, ENT_COMPAT, "ISO-8859-1");
// then only to display in your page, revert it back to utf-8
echo iconv("ISO-8859-1", "UTF-8", $out_iso8859);

I suggest you take a look at http://php.net/html_entity_decode. You can use this in the following way:
我建议你看看http://php.net/html_entity_decode。您可以通过以下方式使用它：
$eacute = html_entity_decode("é",ENT_COMPAT,"iso-8859-1");
This way you don't have to care about the encoding of the php file. edit: typo
这样你就不用关心 php 文件的编码了。编辑：错字

I have added htmlspecialchars for you to see that it is really encoded
我已经为你添加了 htmlspecialchars 以查看它是否真的被编码

<?PHP
echo htmlspecialchars(htmlentities("é", ENT_COMPAT | ENT_HTML401, "UTF-8"));

If you have stored the special characters as é, then you could use the following soon after making connection to the database.
如果您已将特殊字符存储为 é，那么您可以在连接到database.
mysql_set_charset('utf8', $dbHandler);
With this, you now don't need to use htmlentitieswhile displaying data.
有了这个，您现在不需要htmlentities在显示数据时使用。
