PHP DOMDocument不保留HTML特殊字符的数字表示

Question

I have a DOMDocument and would like to append some nodes.

In one of the nodes, I would like to put:

$copyrightStatementText = "© This is the CopyRight";

The problem is that the function:

$copyrightStatement = $dom_output->createElement('copyright-statement', $copyrightStatementText);

Is converting the © immediately to ©.

My goal is to keep the ©

Any idea how could I do that?

From DOMDocument::createElement():

Note: The value will not be escaped. Use DOMDocument::createTextNode() to create a text node with escaping support.

So use DOMDocument::createTextNode() instead:

$copyrightString = "© This is the Copyright";
$copyrightNode = $dom_output->createTextNode($copyrightString);
$copyrightContainer = $dom_output->createElement('copyright-statement');

$copyrightContainer->appendChild($copyrightNode);
