 New Comment:

I am reopening this as PHP 6 is not developed any more and the bug is
still valid.

Won't fix in PHP 5. This will be implemented for PHP 6.

Description:
------------
Simply put, basename() does ot work with Japanese filepaths. If the
filename is Japanese only the extension part of the filename is
returned. So a filename "/folder/ƒtƒ@ƒCƒ‹–¼.txt" resolves to just
".txt". I discovered the problem when performing a basename() on the
$_FILES array's 'name' element for uploaded Japanese files, however
after testing the bug occurs no matter how you supply the filename.



My PHP environment is running with UTF-8 internal encoding.



The code snippet below illustrates this perfectly.

Reproduce code:
---------------
<?php

// show normal behavior with roman filename

$filename='/myfolder/roman_filename.txt';

echo "The full filename of the romanized file is $filename.\n"; //
/myfolder/roman_filename.txt

$basename=basename($filename);

echo "The basename of the romanized file is $basename.\n"; //
/roman_filename.txt

// show behavior with Japanese filename

$filename='/myfolder/“ú–{Œê‚̃tƒ@ƒCƒ‹–¼.txt';

echo "The full filename of the Japanese file is $filename.\n"; //
/myfolder/“ú–{Œê‚̃tƒ@ƒCƒ‹–¼.txt

$basename=basename($filename);

echo "The basename of the Japanese file is $basename."; // .txt

?>

Expected result:
----------------
The full filename of the romanized file is
/myfolder/roman_filename.txt.

The basename of the romanized file is roman_filename.txt.

The full filename of the Japanese file is
/myfolder/“ú–{Œê‚̃tƒ@ƒCƒ‹–¼.txt.

The basename of the Japanese file is “ú–{Œê‚̃tƒ@ƒCƒ‹–¼.txt.

Actual result:
--------------
The full filename of the romanized file is
/myfolder/roman_filename.txt.

The basename of the romanized file is roman_filename.txt.

The full filename of the Japanese file is
/myfolder/“ú–{Œê‚̃tƒ@ƒCƒ‹–¼.txt.

The basename of the Japanese file is .txt.
