推荐答案

设置 nodeValue 属性:

$el = $dom->getElementById('foo');
$el->nodeValue = 'hello world';

请注意，这会自动转义<和>，因此您不能插入这样的HTML.为此，您必须执行 DOMDocument::createDocumentFragment 这样的操作:

Note that this automatically escapes < and >, so you can't insert HTML like this. For that you'll have to do something like DOMDocument::createDocumentFragment:

$frag = $dom->createDocumentFragment();
$frag->appendXML('<h1>foo</h1>');
$el->appendChild($frag);
