Operating system: Windows
PHP version: 5.4.14
Package: Filesystem function related
Bug Type: Bug
Bug description:is_dir() is inaccurate result on Windows with japanese locale.
Description:
Environment
I'm testing this problem on Windows 7 Ultimate x86 english.
Configuration changes little is required to reproduce.
1. Please open "Control Panel".
2. Please click "Change display language" link.
3. Please select "Administrative" tab and click "Change system locale..."
button.
4. Please change current system locale "Japanese(Japan)".
The above procedure is not needed if you want to try in the Japanese
versions of
Windows.
php in immediately after installation, the default state is also php.ini
(does
not exist).
Problem
is_dir() will lie If you create a folder that contains the "\x5C" in the
string.
It may is included in the second byte of Shift_JIS.
For example ã½(\x83\x5C).
More example:
https://ja.wikipedia.org/wiki/Shift_JIS (japanese)
Test script:
---
@mkdir("a");
@mkdir("\x83\x5D");
@mkdir("\x83\x5C");
$dir = './';
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
$path = $dir . $file;
$type = filetype($path);
$type2= is_dir($path) ? 'dir' : 'file';
$comp = $type == $type2 ? 'OK' : 'NG';
echo "filetype()[".str_pad($type, 4)."] ==
is_dir()[".str_pad($type2, 4)."] -> $comp: {$file}\n";
}
closedir($dh);
}
Expected result:
filetype()[dir ] == is_dir()[dir ] -> OK: .
filetype()[dir ] == is_dir()[dir ] -> OK: ..
filetype()[dir ] == is_dir()[dir ] -> OK: a
filetype()[file] == is_dir()[file] -> OK: test.php
filetype()[dir ] == is_dir()[file] -> NG: ã½
filetype()[dir ] == is_dir()[dir ] -> OK: ã¾
Actual result:
--
filetype()[dir ] == is_dir()[dir ] -> OK: .
filetype()[dir ] == is_dir()[dir ] -> OK: ..
filetype()[dir ] == is_dir()[dir ] -> OK: a
filetype()[file] == is_dir()[file] -> OK: test.php
filetype()[dir ] == is_dir()[dir ] -> OK: ã½
filetype()[dir ] == is_dir()[dir ] -> OK: ã¾

Thank you.
I hope a major version.
Incidentally, php-wfio is not work.
Because is_dir() is not implemented.

For the record, it is not that it won't be fixed but can't be fixed at this
stage
but in a major version. Not only PHP's code and not only for file stream
wrapper.

Hi.
It is known problem. And it won't be fixed.
If you need a patch, check my one at:
https://bugs.php.net/bug.php?id=61315
Or you can try php-wfio extension instead.
https://code.google.com/p/php-wfio/
It needs to be built manually with step by step instruction.

Try at your own risk!
Thanks
