如何以UTF-8格式写入文件?

问题描述

我有一堆不是 UTF-8 编码的文件，我正在将网站转换为 UTF-8 编码.

I have bunch of files that are not in UTF-8 encoding and I'm converting a site to UTF-8 encoding.

我对要保存为 utf-8 的文件使用了简单的脚本，但这些文件以旧编码保存:

I'm using simple script for files that I want to save in utf-8, but the files are saved in old encoding:

header('Content-type: text/html; charset=utf-8');
mb_internal_encoding('UTF-8');
$fpath="folder";
$d=dir($fpath);
while (False !== ($a = $d->read()))
 {

 if ($a != '.' and $a != '..')
  {

  $npath=$fpath.'/'.$a;

  $data=file_get_contents($npath);

  file_put_contents('tempfolder/'.$a, $data);

  }

 }

如何以 utf-8 编码保存文件?

推荐答案

file_get_contents/file_put_contents 不会神奇地转换编码.

file_get_contents / file_put_contents will not magically convert encoding.

你必须显式地转换字符串；例如 iconv() 或 mb_convert_encoding().

You have to convert the string explicitly; for example with iconv() or mb_convert_encoding().

试试这个:

$data = file_get_contents($npath);
$data = mb_convert_encoding($data, 'UTF-8', 'OLD-ENCODING');
file_put_contents('tempfolder/'.$a, $data);

或者，使用 PHP 的流过滤器:

Or alternatively, with PHP's stream filters:

$fd = fopen($file, 'r');
stream_filter_append($fd, 'convert.iconv.UTF-8/OLD-ENCODING');
stream_copy_to_stream($fd, fopen($output, 'w'));
