PHP:将 UTF-8 字符串转换为 Ansi? [英] PHP: Converting UTF-8 string to Ansi?

问题描述

我根据数据库中的值构建了一个 csv 字符串.最终的字符串存储在我的 $csv 变量中.

I build a csv string from values I have in my DB. The final string is stored in my $csv variable.

现在我提供此字符串供下载，如下所示:

Now I offer this string for download, like this:

header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=whatever.csv");
header("Pragma: no-cache");
header("Expires: 0");

echo $csv;

例如，当我在 Notepad++ 中打开它时，它显示 Ansi as UTF-8.我如何才能将其更改为仅 Ansi?

When I open this in Notepad++ for example, it says Ansi as UTF-8. How can I chnage that to Ansi only?

我试过了:

$csv = iconv("ISO-8859-1", "WINDOWS-1252", $csv);

这并没有改变任何东西.

That did not change anything.

谢谢！

解决方案:$csv = iconv("UTF-8", "WINDOWS-1252", $csv);

Solution: $csv = iconv("UTF-8", "WINDOWS-1252", $csv);

推荐答案

尝试:

$csv = iconv("UTF-8", "Windows-1252", $csv);

但你最终会丢失数据，因为 ANSI 只能编码一小部分 UTF-8.如果您没有非常强烈的理由反对它，请提供 UTF-8 编码的文件.

But you will eventually lose data because ANSI can only encode a small subset of UTF-8. If you don't have a very strong reason against it, serve your files UTF-8 encoded.
