要素に対して簡単な操作を実行しようとしています。 HTMLファイルが読み込まれ、要素のIDがはっきりと表示されます。以下のエラーログには警告が表示されます。それは警告なので、要素操作コードを実行しないと思います。私は警告を押さえることができます。ええ、エコーはどこにも表示されません。PHP DOMDocumentを使用して要素を操作できないのはなぜですか？
PHP
$doc = new DOMDocument();
$doc->loadHTMLFile('../index.html');
$elem = $doc->getElementById('message');
var_dump("elem=" . $elem);
if ($result == 1) {
$elem->innerHTML = 'File uploaded.';
} else {
$elem->setAttribute("background-color", "red");
$elem->innerHTML = 'Upload failed.';
}
