問題描述

我無法使用 mkdir 創建帶有 UTF-8 字符的文件夾:

I can't use mkdir to create folders with UTF-8 characters:

<?php
$dir_name = "Depósito";
mkdir($dir_name);
?>

當我在 Windows 資源管理器中瀏覽此文件夾時，文件夾名稱如下所示:

when I browse this folder in Windows Explorer, the folder name looks like this:

Dep?3sito

我該怎么辦?

我正在使用 php5

推薦答案

Just urlencode 需要作為文件名的字符串. 從 urlencode 返回的所有 字符在文件名(NTFS/HFS/UNIX)中都是有效的，然后你可以只需 urldecode 將文件名恢復為 UTF-8(或它們采用的任何編碼).

Just urlencode the string desired as a filename. All characters returned from urlencode are valid in filenames (NTFS/HFS/UNIX), then you can just urldecode the filenames back to UTF-8 (or whatever encoding they were in).

注意事項(也適用于以下解決方案):

Caveats (all apply to the solutions below as well):

• 經過 url 編碼后，文件名必須少于 255 個字符(可能是字節).
• UTF-8 對許多字符具有多種表示(使用組合字符).如果您不規范化 UTF-8，則可能無法使用 glob 進行搜索或重新打開單個文件.
• 您不能依賴 scandir 或類似函數進行 alpha 排序.您必須 urldecode 文件名，然后使用識別 UTF-8(和排序規則)的排序算法.

• After url-encoding, the filename must be less that 255 characters (probably bytes).
• UTF-8 has multiple representations for many characters (using combining characters). If you don't normalize your UTF-8, you may have trouble searching with glob or reopening an individual file.
• You can't rely on scandir or similar functions for alpha-sorting. You must urldecode the filenames then use a sorting algorithm aware of UTF-8 (and collations).

以下是不太吸引人的解決方案，但更復雜，但有更多注意事項.

The following are less attractive solutions, more complicated and with more caveats.

在 Windows 上，PHP 文件系統包裝器期望并返回文件/目錄名稱的 ISO-8859-1 字符串.這給了你兩個選擇:

On Windows, the PHP filesystem wrapper expects and returns ISO-8859-1 strings for file/directory names. This gives you two choices:

1. 在您的文件名中自由使用 UTF-8，但要了解非 ASCII 字符在 PHP 之外看起來不正確.非 ASCII UTF-8 字符將存儲為多個 單個 ISO-8859-1 字符.例如.ó 在 Windows 資源管理器中將顯示為 ?3.

1. Use UTF-8 freely in your filenames, but understand that non-ASCII characters will appear incorrect outside PHP. A non-ASCII UTF-8 char will be stored as multiple single ISO-8859-1 characters. E.g. ó will be appear as ?3 in Windows Explorer.

將您的文件/目錄名稱限制為字符可在 ISO-8859-1 中表示.在實踐中，您將在使用之前通過 utf8_decode 傳遞 UTF-8 字符串在文件系統函數中，并傳遞條目 scandir 通過 utf8_encode 以獲取 UTF-8 格式的原始文件名.

Limit your file/directory names to characters representable in ISO-8859-1. In practice, you'll pass your UTF-8 strings through utf8_decode before using them in filesystem functions, and pass the entries scandir gives you through utf8_encode to get the original filenames in UTF-8.

大量警告！

• 如果傳遞給文件系統函數的任何字節匹配無效的WindowsISO-8859-1 中的文件系統字符，你運氣不好.
• Windows 可能在非英語語言環境中使用除 ISO-8859-1 以外的編碼.我猜它通常是 ISO-8859-# 之一，但這意味著您需要使用 mb_convert_encoding 而不是 utf8_decode.

• If any byte passed to a filesystem function matches an invalid Windows filesystem character in ISO-8859-1, you're out of luck.
• Windows may use an encoding other than ISO-8859-1 in non-English locales. I'd guess it will usually be one of ISO-8859-#, but this means you'll need to use mb_convert_encoding instead of utf8_decode.

這個噩夢就是為什么你應該音譯來創建文件名.

This nightmare is why you should probably just transliterate to create filenames.
