How do I use filesystem functions in PHP, using UTF-8 strings?

Question

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

Answer 1

Using the com_dotnet PHP extension, you can access Windows' Scripting.FileSystemObject, and then do everything you want with UTF-8 files/folders names.

I packaged this as a PHP stream wrapper, so it's very easy to use :

https://github.com/nicolas-grekas/Patchwork-UTF8/blob/lab-windows-fs/class/Patchwork/Utf8/WinFsStreamWrapper.php

First verify that the com_dotnet extension is enabled in your php.ini then enable the wrapper with:

stream_wrapper_register('win', 'Patchwork\Utf8\WinFsStreamWrapper');

Finally, use the functions you're used to (mkdir, fopen, rename, etc.), but prefix your path with win://

For example:

<?php
$dir_name = "Depósito";
mkdir('win://' . $dir_name );
?>

Try CodeIgniter Text helper from this link Read about convert_accented_characters() function, it can be costumised

Answer 3

You could use this extension to solve your issue: https://github.com/kenjiuno/php-wfio

$file = fopen("wfio://多国語.txt", "rb"); // in UTF-8
....
fclose($file);

Answer 4

The problem is that Windows uses utf-16 for filesystem strings, whereas Linux and others use different character sets, but often utf-8. You provided a utf-8 string, but this is interpreted as another 8-bit character set encoding in Windows, maybe Latin-1, and then the non-ascii character, which is encoded with 2 bytes in utf-8, is handled as if it was 2 characters in Windows.

A normal solution is to keep your source code 100% in ascii, and to have strings somewhere else.

Answer 5

I don't need to write much, it works well:

<?php
$dir_name = mb_convert_encoding("Depósito", "ISO-8859-1", "UTF-8");
mkdir($dir_name);
?>

My set of tools to use filesystem with UTF-8 on windows OR linux via PHP and compatible with .htaccess check file exists:

function define_cur_os(){

    //$cur_os=strtolower(php_uname());

    $cur_os=strtolower(PHP_OS);

    if(substr($cur_os, 0, 3) === 'win'){

        $cur_os='windows';

    }

    define('CUR_OS',$cur_os);

}

function filesystem_encode($file_name=''){

    $file_name=urldecode($file_name);

    if(CUR_OS=='windows'){

        $file_name=iconv("UTF-8", "ISO-8859-1//TRANSLIT", $file_name);

    }     

    return $file_name;

}

function custom_mkdir($dir_path='', $chmod=0755){

    $dir_path=filesystem_encode($dir_path);

    if(!is_dir($dir_path)){

        if(!mkdir($dir_path, $chmod, true)){

            //handle mkdir error

        }
    }
    return $dir_path;
}

function custom_fopen($dir_path='', $file_name='', $mode='w'){

    if($dir_path!='' && $file_name!=''){

        $dir_path=custom_mkdir($dir_path);

        $file_name=filesystem_encode($file_name);

        return fopen($dir_path.$file_name, $mode);

    }

    return false;

}

function custom_file_exists($file_path=''){

    $file_path=filesystem_encode($file_path);

    return file_exists($file_path);

}

function custom_file_get_contents($file_path=''){

    $file_path=filesystem_encode($file_path);

    return file_get_contents($file_path);

}
