Header, Nav and Section are elements from HTML5. Because HTML5 developers felt it is too difficult to remember Public and System Identifiers, the DocType declaration is just:
Header、Nav 和 Section 是来自 HTML5 的元素。因为 HTML5 开发人员觉得公共标识符和系统标识符太难记住，所以 DocType 声明只是：
<!DOCTYPE html>
In other words, there is no DTD to check, which will make DOM use the HTML4 Transitional DTD and that doesnt contain those elements, hence the Warnings.
换句话说，没有要检查的 DTD，这将使 DOM 使用 HTML4 Transitional DTD 并且不包含这些元素，因此警告。
To surpress the Warnings, put
为了抑制警告，把
libxml_use_internal_errors(true);
before the call to loadHTMLand
在调用loadHTML和之前
libxml_use_internal_errors(false);
after it.
之后。
An alternative would be to use https://github.com/html5lib/html5lib-php.

With a DOMDocument object, you should be able to place an @ before the load method in order to SUPPRESS all WARNINGS.
对于 DOMDocument 对象，您应该能够在 load 方法之前放置一个 @ 以抑制所有警告。
$dom = new DOMDocument;
@$dom->loadHTML($source);
And carry on.
并继续。
