</body>
</html>
我的程序是这样做的：
$cleanMessage = new DOMDocument();
@$cleanMessage->loadHTML($this->bodyHTML); //To clean the html code for unclosed td table tags and other
$this->message = $cleanMessage->saveHTML();
但我的输出是：
null
我试过：
1.
$this->bodyHTML = mb_convert_encoding($this->bodyHTML,'UTF-8','utf-16');
$this->bodyHTML = mb_convert_encoding($this->bodyHTML,'HTML-ENTITIES','UTF-8'); //both lines together
但仍显示乱码或中文字符。
正确显示此html的正确方法是什么？
在html中，如果看到奇怪的字符，请将字符集UTF-16替换为UTF-8或ISO-8859-1。
$this->bodyHTML = str_replace("charset=utf-16","charset=utf-8", $this->bodyHTML);
