大家好，Web开发大师:) 我有一段PHP脚本，可以从我的winamp中获取最近10首播放的歌曲。这个脚本是内部文件（让我们称之为“lastplayed.php”），它包含在我的网站中，包含在“div”中的php include函数。 我的网站采用UTF-8编码。问题是某些歌曲标题采用Windows-1251编码。在我的网站上，它们显示为“ ”...... 有没有任何已知的方法告诉这个div，其中包含“lastplayed.php”，与windows-1251编码？ 还是其他任何建议？
P.S：带有脚本a.k.a.“lastplayed.php”的文件被转换为UTF-8。但如果它是ANCII，那就是同样的结果。我尝试在头标签之间添加带有windows-1251的meta标签，但没有任何反复发生。
P.P.S：获取Winamp数据的脚本（lastplayed.php）：

echo $radio->getHistoryTable("/played.html", "<b>Last played:</b>", "lastplayed_content");

如果所有源数据都在windows-1251中，您可以使用以下内容：
$title_utf8=mb_convert_encoding($title,"utf-8","Windows-1251")
并将转换后的数据放入HTML流中。
由于我只关注文档，因此我不能100％确定源编码别名是正确的;如果Windows-1251不起作用，您可能需要尝试使用CP1251。
如果你的源数据在1251年不可靠，你将不得不想出一个启发式猜测，并使用相同的转换方法。 mb_detect_encoding可以帮到你。
您无法更改HTML文档的部分编码，但您可以轻松地将所有内容转换为UTF-8。
较新的ID3实现在其文本框架中具有编码标记：
$00 ISO-8859-1 (ASCII)
$01 – UCS-2 in ID3v2.2 and ID3v2.3, UTF-16 encoded Unicode with BOM.
$02 – UTF-16BE encoded Unicode without BOM in ID3v2.4 only.
$03 – UTF-8 encoded Unicode in ID3v2.4 only.
您的内容是否可能是UTF16？
根据您发布的代码，目前尚不清楚$ trackArr是如何定义的，因为它没有在其他地方引用。看起来你有几个问题。
$title_utf8 = mb_convert_encoding($trackArr ,"utf-8" ,"auto")
“auto”扩展为不包含Windows-1251的编码列表，所以我不确定你为什么使用它。你真的应该使用“Windows-1251”。我已经尝试在安装了PHP的Mac上使用“Windows-1251，utf-16”，但是自动检测无法针对相对较短的字符串找到合适的编码，所以看起来你将不得不成为猜测的那个
但是，当您使用迭代覆盖值时，该代码看起来似乎没有任何理由存在：
foreach ($this->tracks AS $title_utf8)
$output .= "<div style='padding:2px 0;'>".$title_utf8['track'].\"</div>";
在每次迭代中，变量$title_utf8被分配给当前轨道。您可能想要的更像是：
foreach ($this->tracks AS $current_track)
$output .= "<div style='padding:2px 0;'>". mb_convert_encoding($current_track ,"utf-8" ,"Windows-1251");
mb_convert_encoding将字符串作为第一个参数，而不是数组或对象，因此您需要对每个不是utf-8的字符串应用此编码。
