如何以UTF-8格式写文件?

我有一堆非UTF-8编码的文件,我正在将网站转换为UTF-8编码。

我正在使用简单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);

  }

 }

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

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,使用iconv()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'));

<?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); 
} 
?>

在Unix / Linux上,可以使用简单的shell命令来转换给定目录中的所有文件:

 recode L1..UTF8 dir/*

也可以通过PHP exec()启动。

如果要递归使用recode,并过滤类型,请尝试:

find . -name "*.html" -exec recode L1..UTF8 {} \;

这对我有用。 :)

$f=fopen($filename,"w"); 
# Now UTF-8 - Add byte order mark 
fwrite($f, pack("CCC",0xef,0xbb,0xbf)); 
fwrite($f,$content); 
fclose($f);

这是一个非常有用的问题。我认为我的Windows 10 PHP7解决方案对仍然存在UTF-8转换麻烦的人很有用。

这是我的步骤。调用以下函数(此处名为 utfsave.php )的PHP脚本本身必须具有UTF-8编码,可以通过在UltraEdit上进行转换来轻松实现。

在utfsave.php中,我们定义了一个调用PHP fopen($ filename,“ wb ”)的函数,即,它以w写模式打开,尤其是在 binary中使用b 模式。

<?php
//
//  UTF-8 编码:
//
// fnc001: save string as a file in UTF-8:
// The resulting file is UTF-8 only if $strContent is,
// with French accents, chinese ideograms, etc..
//
function entSaveAsUtf8($strContent, $filename) {
  $fp = fopen($filename, "wb"); 
  fwrite($fp, $strContent);
  fclose($fp);
  return True;
}

//
// 0. write UTF-8 string in fly into UTF-8 file:
//
$strContent = "My string contains UTF-8 chars ie 鱼肉酒菜 for un été en France";

$filename = "utf8text.txt";

entSaveAsUtf8($strContent, $filename);


//
// 2. convert CP936 ANSI/OEM - chinese simplified GBK file into UTF-8 file:
//
$strContent = file_get_contents("cp936gbktext.txt");
$strContent = mb_convert_encoding($strContent, "UTF-8", "CP936");


$filename = "utf8text2.txt";

entSaveAsUtf8($strContent, $filename);

?>

源文件cp936gbktext.txt的文件内容:

>>Get-Content cp936gbktext.txt
My string contains UTF-8 chars ie 鱼肉酒菜 for un été en France 936 (ANSI/OEM - chinois simplifié GBK)

在Windows 10 PHP上运行 utf8save.php ,这样创建的 utf8text.txt utf8text2.txt 文件将自动保存在UTF- 8种格式。

使用此方法,不需要BOM字符。 BOM解决方案之所以不好,是因为它在例如为MySQL采购sql文件时会引起麻烦。

值得注意的是,我为此无法完成工作 file_put_contents($ filename,utf8_encode($ mystring));

如果您不知道源文件的编码,则可以使用PHP列出编码:

print_r(mb_list_encodings());

这给出了这样的列表:

如果您无法猜测,请一一尝试,因为mb_detect_encoding()无法轻松完成这项工作。

我把所有内容放在一起,很容易将ANSI文本文件转换为“UTF-8 No Mark”:

function filesToUTF8($searchdir,$convdir,$filetypes) {
  $get_files = glob($searchdir.'*{'.$filetypes.'}', GLOB_BRACE);
  foreach($get_files as $file) {
    $expl_path = explode('/',$file);
    $filename = end($expl_path);
    $get_file_content = file_get_contents($file);
    $new_file_content = iconv(mb_detect_encoding($get_file_content, mb_detect_order(), true), "UTF-8", $get_file_content);
    $put_new_file = file_put_contents($convdir.$filename,$new_file_content);
  }
}

用法:filesToUTF8('C:/ Temp /','C:/ Temp / conv_files /','php,txt');
