php - 如何修复 saveHTML()：由于转换错误导致输出转换失败？

Question

应该适用于任何网址的简单代码（我认为）：

我不知道为什么我会收到以下警告。任何想法 ？

PHP 警告：DOMDocument::saveHTML(): output conversion failed due to conv error, bytes 0xE9 0x74 0xC3 0xA9 in ********.php on line 9

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

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

您是否尝试过强制UTF-8 编码，将 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：

$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();
