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/?t?@?C????.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/???{???̃t?@?C????.txt';
echo "The full filename of the Japanese file is $filename.\n"; // /myfolder/???{???̃t?@?C????.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/???{???̃t?@?C????.txt.
The basename of the Japanese file is ???{???̃t?@?C????.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/???{???̃t?@?C????.txt.
The basename of the Japanese file is .txt.

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

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

For better or worse, basename is affected by the locale. The encoding used in the filenames must match the set locale.

Bogus.

we want to use many locales and we don't know locale of filename before user add file. how we can use this filenames without transliteration?

On PHP 5.5.1 Windows, I got the results below if I put "setlocale(LC_ALL, 'japanese');".

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/日本語のファイル名.txt.
The basename of the Japanese file is 日本語のファイル名.txt.

Just gave the following a test with PHP 5.5.5:

<?php

echo
  basename(__DIR__ . "/english.txt") , PHP_EOL ,
  basename(__DIR__ . "/日本語.txt") , PHP_EOL ,
  basename(__DIR__ . "/ελληνικά.txt") , PHP_EOL ,
  basename(__DIR__ . "/english.txt", "txt") , PHP_EOL ,
  basename(__DIR__ . "/日本語.txt", "txt") , PHP_EOL ,
  basename(__DIR__ . "/ελληνικά.txt", "txt") , PHP_EOL
;

?>

Everything was returned correctly by PHP, LC of the server was set to POSIX.
