在PHP中编写UTF-8编码文件的问题 [英] Problem writing UTF-8 encoded file in PHP

问题描述

我有一个大文件，其中包含世界各国/地区，我根据个别国家/地区划分为较小的文件。原始文件包含以下条目：

  EE.04Järvamaa
 EE.05Jõgevamaa
 EE.07然而，当我提取它并将其写入一个新文件时，文本变为：
 
 > 
 
 
  EE.04Järvamaa
 EE.05JÃμgevamaa
 EE.07Lään¤ b 
要保存文件，我使用以下代码：
  mb_detect_encoding（$ text，UTF-8）==UTF-8？ ：$ text = utf8_encode（$ text）; 
 $ fp = fopen（MY_LOCATION，'wb'）; 
 fwrite（$ fp，$ text）; 
 fclose（$ fp）; 
 
我尝试保存文件有和没有utf8_encode（）和似乎都不工作。我将如何保存原始编码（即UTF8）？
 
 
 
谢谢！
解决方案
首先，不要依赖 mb_detect_encoding 。除非有一堆编码特定实体（意味着在其他编码中无效的实体），否则找出该编码是不是很好。
 
 
 
尝试摆脱 mb_detect_encoding 一起。
 
 
 
哦，和  utf8_encode  打开 Latin-1 字符串转换为 UTF-8 字符串（不是从任意字符集到 UTF-8 这是你真正想要的）...你想  iconv  ，但您需要知道源代码（因为您不能真正信任 mb_detect_encoding ，您需要找出一些其他方式）。 
 
 
 
或者您可以尝试使用 iconv 输入空输入编码 $ str = iconv ''，'UTF-8'，$ str）; （可能或可能不工作）... 
 
I have a large file that contains world countries/regions that I'm seperating into smaller files based on individual countries/regions. The original file contains entries like:
  EE.04 Järvamaa
  EE.05 Jõgevamaa
  EE.07 Läänemaa
However when I extract that and write it to a new file, the text becomes:
  EE.04  Järvamaa
  EE.05  Jõgevamaa
  EE.07  Läänemaa
To save my files I'm using the following code:
mb_detect_encoding($text, "UTF-8") == "UTF-8" ? : $text = utf8_encode($text);
$fp = fopen(MY_LOCATION,'wb');
fwrite($fp,$text);
fclose($fp);
I tried saving the files with and without utf8_encode() and neither seems to work. How would I go about saving the original encoding (which is UTF8)?

Thank you!
解决方案
First off, don't depend on mb_detect_encoding.  It's not great at figuring out what the encoding is unless there's a bunch of encoding specific entities (meaning entities that are invalid in other encodings).

Try just getting rid of the mb_detect_encoding line all together.

Oh, and utf8_encode turns a Latin-1 string into a UTF-8 string (not from an arbitrary charset to UTF-8, which is what you really want)...  You want iconv, but you need to know the source encoding (and since you can't really trust mb_detect_encoding, you'll need to figure it out some other way). 

Or you can try using iconv with a empty input encoding $str = iconv('', 'UTF-8', $str); (which may or may not work)...
