如何在PHP中设置文本文件编码？ [英] How to set text file encoding in PHP?

问题描述

如何在PHP中设置文本文件ENCODING（例如UTF-8）？

让我告诉你我的问题。这是我的代码：

 <？php 
 file_put_contents（'test.txt'，$ data）; //数据是一些带有UTF-8字符集的非英语文本
？> 
  

输出：اÙ！

fwrite（）有类似的输出。

当我通过记事本创建 test.txt 并设置字符集 UTF-8 的输出是我想要的。
我想在PHP文件中设置字符集。

现在这是我的问题：如何通过PHP设置文本文件编码？

解决方案

PHP在文件中存储文本时不应用编码：它存储的数据完全按照字符串中的布局。

您提到在 notepad.exe 中打开文件时出现问题。该文本编辑器不是很擅长猜测你打开的文件的编码;如果文本以UTF-8编码，则必须选择将其打开为UTF-8。如果可能，请使用其他文本编辑器。 记事本++ 是常见的替代品。

如果必须使用 notepad.exe ，作为最后手段，请写一个字节顺序标记该文件在你写任何东西之前;这将使它将文件识别为UTF-8，同时可能使文件无法用于其他目的（有关详细信息，请参阅维基百科文章）。

  file_put_contents（file.txt，\xEF\xBB\xBF。$ data）; 
  

How can I set a text file ENCODING (for instance UTF-8) in PHP?

Let me show you my problem. This is my code:

<?php 
file_put_contents('test.txt', $data); // data is some non-English text with UTF-8 charset
?>

Output: اÙ!

fwrite() has the similar output.

But when I create the test.txt by notepad and set the charset UTF-8 the output is what I want. I wanna set the charset in the PHP file.

Now this is my question: How to set text file encoding by PHP?

解决方案

PHP does not apply an encoding when storing text in a file: it stores data exactly as it is laid out in the string.

You mention that you have problems opening the file in notepad.exe. That text editor is not very good at guessing the encoding of the file you are opening; if the text is encoded in UTF-8 you must choose to open it as UTF-8. Use another text editor if possible. Notepad++ is a popular replacement.

If you must use notepad.exe, as a last resort, write a Byte Order Mark to the file before you write anything else; this will make it recognize the file as UTF-8 while potentially making the file unusable for other purposes (see the Wikipedia article for details).

file_put_contents("file.txt", "\xEF\xBB\xBF" . $data);
