PHP:每当我尝试编写 UTF-8 时，它都会使用 DOMDocument 写入它的十六进制表示法
当我尝试使用 DOMDocument 将 UTF-8 字符串写入 XML 文件时，它实际上写入的是字符串的十六进制表示法，而不是字符串本身.
When I try to write UTF-8 Strings into an XML file using DOMDocument it actually writes the hexadecimal notation of the string instead of the string itself.
例如:
ירושלים
代替:
ירושלים
有什么想法可以解决这个问题吗?
Any ideas how to resolve the issue?
推荐答案
好的，给你:
$dom = new DOMDocument('1.0', 'utf-8');
$dom->appendChild($dom->createElement('root'));
$dom->documentElement->appendChild(new DOMText('ירושלים'));
echo $dom->saveXml();
会正常工作，因为在这种情况下，您构建的文档将保留指定为第二个参数的编码:
will work fine, because in this case, the document you constructed will retain the encoding specified as the second argument:
<?xml version="1.0" encoding="utf-8"?>
<root>ירושלים</root>
但是，一旦将 XML 加载到未指定编码的 Document 中，您将丢失在构造函数中声明的任何内容，这意味着:
However, once you load XML into a Document that does not specify an encoding, you will lose anything you declared in the constructor, which means:
$dom = new DOMDocument('1.0', 'utf-8');
$dom->loadXml('<root/>'); // missing prolog
$dom->documentElement->appendChild(new DOMText('ירושלים'));
echo $dom->saveXml();
不会有 utf-8 编码:
will not have an encoding of utf-8:
<?xml version="1.0"?>
<root>ירושלים</root>
因此，如果您加载 XML 内容，请确保它是
So if you loadXML something, make sure it is
$dom = new DOMDocument();
$dom->loadXml('<?xml version="1.0" encoding="utf-8"?><root/>');
$dom->documentElement->appendChild(new DOMText('ירושלים'));
echo $dom->saveXml();
它会按预期工作.
作为替代，您也可以指定编码 加载文档后.
As an alternative, you can also specify the encoding after loading the document.
