Php 如何以UTF-8格式写入文件？,php,encoding,utf-8,iconv,mbstring,Php,Encoding,Utf 8,Iconv,Mbstring,我有很多不是UTF-8编码的文件，我正在将一个站点转换为UTF-8编码 我正在使用简单脚本保存我想以utf-8格式保存的文件，但这些文件是以旧编码保存的： 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 != '.'

我有很多不是UTF-8编码的文件，我正在将一个站点转换为UTF-8编码

我正在使用简单脚本保存我想以utf-8格式保存的文件，但这些文件是以旧编码保存的：

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？

文件获取内容/文件放置内容不会神奇地转换编码

您必须显式地转换字符串；例如使用或

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'));
营救。

在Unix/Linux上，也可以使用一个简单的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PHPs exec（）启动。

添加BOM:UTF-8

file_put_contents($myFile, "\xEF\xBB\xBF".  $content);
如果要递归使用recode并对类型进行筛选，请尝试以下操作：

find . -name "*.html" -exec recode L1..UTF8 {} \;
这对我有用。：）

我从你那儿收到这封信

  • 在windows笔记本中打开文件
  • 将编码更改为UTF-8编码
  • 保存您的文件
  • 再试一次！：O）
    • 我将所有这些放在一起，得到了将ANSI文本文件转换为“UTF-8无标记”的简单方法：

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

    这是一个非常有用的问题。我认为我在Windows10PHP7上的解决方案对于那些还存在UTF-8转换问题的人来说非常有用

    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，这可以通过UltraEdit上的转换轻松完成

    在utfsave.php中，我们定义了一个调用php fopen（$filename，“wb”）的函数，也就是说，它是在w写入模式下打开的，尤其是在b写入模式下

    <?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);

?>
    在Windows 10 php上运行utf8save.php，从而创建utf8text.txt，utf8text2.txt文件将自动以UTF-8格式保存

    使用此方法，不需要BOM字符。BOM解决方案很糟糕，因为当我们为MySQL寻找sql文件时，它会带来麻烦

    值得注意的是，我没能制作出文件内容（$filename，utf8_encode（$mystring））为此目的

    print_r(mb_list_encodings());

    不知道此命令。谢谢我使用Linux作为工作站，我所有的本地服务器都在Linux上。L1.是什么意思。。命令中的意思是？@Starmaster:L1是源字符集拉丁文-1的简写。我试图创建一个php下载脚本，以便将UTF-8用于丹麦字符，这是它所缺少的，tyIt也适用于UTF-16，但使用该字节：fwrite（$f，pack（“CC”，0xff，0xfe））；这对我来说是有效的，下载用utf编码的aspx页面到windows平台上。这应该是公认的答案。。。又短又甜，很管用！创建一个被识别为UTF-8的文件和转换该文件的内容是有区别的。没有特殊字符的纯文本文件具有与没有BOM的UTF-8相同的内容，并且可能正在处理文本的解析器具有编码选项。PHP本身使用UTF-8，所以如果您看到文本OK但文件似乎不是UTF-8，那么很可能文本是UTF-8，添加BOM就是您所需要的。但是，这不是转换。这个问题经常出现，因为PHP懒散地添加BOM，但它本身也希望在输入时添加BOM。我的问题与OP略有不同，但这解决了我的问题。我没有使用file\u put\u内容，而是使用header立即下载文件。数据已经在数据库中的UTF-8中，但在CSV下载中无法使用。这很有效。谢谢。第一个示例第3行的$a变量是什么？如果使用流\u过滤器\u附加：OLD-ENCODING/UTF-8 
    function filesToUTF8($searchdir,$convdir,$filetypes) {
  $get_files = glob($searchdir.'*{'.$filetypes.'}', GLOB_BRACE);
