如何以UTF-8格式写文件？

Question

我有一堆不是UTF-8编码的文件,我正在将一个站点转换为UTF-8编码.

我正在使用简单的脚本来保存我想要保存在utf-8中的文件,但文件以旧编码保存:

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？

Answer 1

添加物料清单:UTF-8

file_put_contents($myFile, "\xEF\xBB\xBF".  $content); 

Answer 2

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

你必须明确地转换字符串; 例如用iconv()或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:

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

Answer 3

<?php
function writeUTF8File($filename,$content) { 
        $f=fopen($filename,"w"); 
        # Now UTF-8 - Add byte order mark 
        fwrite($f, pack("CCC",0xef,0xbb,0xbf)); 
        fwrite($f,$content); 
        fclose($f); 
} 
?>
