推荐答案

您是否尝试强制 UTF-8编码，从iso-8859-1转换为UTF-8？我刚才有一个类似的问题，它对我有用。也许尝试：

Have you tried to force UTF-8 encoding, which converts from iso-8859-1 to UTF-8? I had a similar issue just now, and it worked for me. Maybe try:

$content = file_get_contents('http://www.ludibay.net/');
$content = utf8_encode($content); // convert $content to utf_8
$encoding = mb_detect_encoding($content);
$doc = new DomDocument();

$res = @$doc->loadHTML('<?xml encoding="'.$encoding.'">'.$content);
//some treatment on nodes here
echo $doc->saveHTML();
