DOMDocument：：loadHTML（）： warning - htmlParseEntityRef： Entity 中没有名称

我发现了几个类似的问题，但到目前为止，还没有一个能够帮助我。

我正在尝试在HTML块中输出所有图像的“src”，所以我正在使用.这种方法确实有效，但我在某些页面上收到警告，我无法弄清楚原因。一些帖子建议压制警告，但我宁愿找出为什么生成警告。DOMDocument()

警告： DOMDocument：：loadHTML（）： htmlParseEntityRef： Entity 中没有名称， 行： 10

生成错误的一个例子是 -post->post_content

$dom = new DOMDocument();
$dom->loadHTML(apply_filters('the_content', $post->post_content)); // Have tried stripping all tags but <img>, still generates warning
$nodes = $dom->getElementsByTagName('img');
foreach($nodes as $img) :
    $images[] = $img->getAttribute('src');
endforeach;
