How to convert accented chars to html in php?
提问by Gabriel
I have foreign language strings stored in utf8. When displaying them, I want them to be transform in such a way that accented chars become their html counterparts, e.g. ébecomes é
我有存储在 utf8 中的外语字符串。在显示它们时，我希望它们以这样的方式进行转换，即重音字符变成它们的 html 对应物，例如é变成é
However I phrase my search, all I can find is htmlentities()which does not do it.
然而，我用我的搜索措辞，我能找到的只是htmlentities()不这样做。

I found this is a very simple solution to this problem.
我发现这是这个问题的一个非常简单的解决方案。
The first part tries to encode the text. If the $output returns a blank string, then the value is utf8 encoded and then the html entities are created.
第一部分尝试对文本进行编码。如果 $output 返回一个空字符串，则该值是 utf8 编码的，然后创建 html 实体。
$output = htmlentities($value, 0, "UTF-8");
if ($output == "") {
$output = htmlentities(utf8_encode($value), 0, "UTF-8");
}
Example:
例子：
Montréal
Output:
输出：
Montréal

Make sure you're properly specifying the encoding when you call htmlentities().
确保在调用时正确指定了编码htmlentities()。
The documentation shows that it defaults to 'UTF-8', but if you read down a bit further, you'll see that that's new as of PHP 5.4. If you're using an older version, the default is actually 'ISO-8859-1', and you'll need to make sure you explicitly specify it as 'UTF-8'instead of relying on the default behaviour.
文档显示它默认为'UTF-8'，但如果您进一步阅读，您会发现这是 PHP 5.4 的新内容。如果您使用的是旧版本，则默认值实际上是'ISO-8859-1'，并且您需要确保将其明确指定为 as'UTF-8'而不是依赖于默认行为。
htmlentities($string, 0, 'UTF-8');
