PHP encoding with DOMDocument
提问by Olivier Lalonde

When I try to get the content of the following code using DOMDocument functions, it returns something like:
当我尝试使用 DOMDocument 函数获取以下代码的内容时，它返回如下内容：
DD?DμDo? D?
I've tried setting DOMDocument encoding to different values (UTF-8, ISO-8859-1), using mb_convert_encoding, iconv and utf8_encode but without success.
我尝试使用 mb_convert_encoding、iconv 和 utf8_encode 将 DOMDocument 编码设置为不同的值（UTF-8、ISO-8859-1），但没有成功。
How can I get "Алекс М" instead of "DD?DμDo? D?" ?
我怎样才能得到“Алекс М”而不是“DD？DμDo？D？” ?
EDIT: The input is coming from a page loaded with curl. When I output the page content to my browser, the characters are displayed correctly (so I doubt the input is the problem).
编辑：输入来自加载了 curl 的页面。当我将页面内容输出到浏览器时，字符显示正确（所以我怀疑输入是问题所在）。

Try:
尝试：
$string = file_get_contents('your-xml-file.xml');
$string = mb_convert_encoding($string, 'utf-8', mb_detect_encoding($string));
// if you have not escaped entities use
$string = mb_convert_encoding($string, 'html-entities', 'utf-8');
$doc = new DOMDocument();
$doc->loadXML($string);

I had a similar problem after using XPath to parse DomDocument, and after reading this
使用 XPath 解析 DomDocument 后，我遇到了类似的问题，并在阅读本文后

I solved it like this
我是这样解决的
// Workaround because PHP 5.2.x has encoding problems, when we
// update to PHP 5.3 this line is not necesserry any more
$content = '<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />' . $content;
// Creating new DOM document and loading HTML content
$dom_document = new DOMDocument('1.0', 'UTF-8');
$dom_document->substituteEntities = TRUE;
$dom_document->loadHTML($content);

Add xml header to you tags - try this:
将 xml 标头添加到您的标签 - 试试这个：
$a = new DOMDocument ();
$a->loadXml ('<?xml version="1.0" encoding="UTF-8"?><tag>Алекс М</tag>');
print htmlspecialchars ($a->saveXml ());
