$linkis an object which can not be converted to string (some objects can).
To see which object it is, use var_dump($link);. I assume it's a DOMElementDocs, see the link for all properties and methods it has to offer, e.g.
要查看它是哪个对象，请使用var_dump($link);。我假设它是一个DOMElementDocs，请参阅它必须提供的所有属性和方法的链接，例如
echo $link->tagName;
or
或者
echo $link->textContent;
