How to set text file encoding in PHP?
提问by Programmer.zip
How can I set a text file ENCODING (for instance UTF-8) in PHP?
如何在 PHP 中设置文本文件编码（例如 UTF-8）？
Let me show you my problem. This is my code:
让我告诉你我的问题。这是我的代码：
<?php
file_put_contents('test.txt', $data); // data is some non-English text with UTF-8 charset
?>
Output: ?§ù!
输出：?§ù！
fwrite()has the similar output.
fwrite()有类似的输出。
But when I create the test.txtby notepad and set the charset UTF-8the output is what I want.
I wanna set the charset in the PHP file.
但是当我创建test.txtby 记事本并设置字符集UTF-8 时，输出就是我想要的。我想在 PHP 文件中设置字符集。
Now this is my question: How to set text file encoding by PHP?
现在这是我的问题：如何通过 PHP 设置文本文件编码？

PHP does not apply an encoding when storing text in a file: it stores data exactly as it is laid out in the string.
PHP 在文件中存储文本时不应用编码：它完全按照字符串中的布局存储数据。
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.
您提到在notepad.exe. 那个文本编辑器不太擅长猜测你打开的文件的编码；如果文本以 UTF-8 编码，您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。Notepad++是一种流行的替代品。
If you must use notepad.exe, as a last resort, write a Byte Order Markto 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).
如果您必须使用notepad.exe，作为最后的手段，请在写入任何其他内容之前将字节顺序标记写入文件；这将使其将文件识别为 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 Wikipedia 文章）。
file_put_contents("file.txt", "\xEF\xBB\xBF" . $data);

You may try this using mb_convert_encoding
您可以尝试使用mb_convert_encoding
$data = mb_convert_encoding($data, 'UTF-8', 'auto');
file_put_contents('test.txt', $data);
Also check iconv.
还要检查iconv。
Update :(try this and find the right encoding for your text)
更新：（试试这个并为您的文本找到正确的编码）
foreach(mb_list_encodings() as $chr){
echo mb_convert_encoding($data, 'UTF-8', $chr)." : ".$chr."<br>";
}
Also, try this on GitHub.
另外，在GitHub 上试试这个。

You can create a function which converts a string array into a utf8 encoded string array and another to decode and write to a notepad file for you.
您可以创建一个函数，将字符串数组转换为 utf8 编码的字符串数组，并为您解码并写入记事本文件。
<?php
function utf8_string_encode(&$array){
$myencode = function(&$value,&$key){
if(is_string($value)){
$value = utf8_encode($value);
}
if(is_string($key)){
$key = utf8_encode($key);
}
if(is_array($value)){
utf8_string_encode($value);
}
};
array_walk($array,$func);
return $array;
}
?>
