Bug #62119 [Com]: basename broken with non-ASCII-chars

Edit report at https://bugs.php.net/bug.php?id=62119&edit=1 ID: 62119 Comment by: christiansen dot jacob at gmail dot com Reported by: thomas dot hebinck at digionline dot de Summary: basename broken with non-ASCII-chars Status: Verified Type: Bug Package: *Directory/Filesystem functions Operating System: Linux/Ubuntu PHP Version: 5.3.13 Block user comment: N Private report: N New Comment: This is still an issue in PHP 5.6 and it is PHP's problem, since PHP roll its own implementation of basename. The problem seems to occur when running basename on a string that have a multibyte char as the first char when LC_TYPE is set to POSIX. Which seems to be default for PHP. On way to solve this is to set the LC_TYPE to UTF-8, but I guess that PHP should handle this.

Interestingly, the system's "basename" binary, which I'd assume is making the same glibc call, does not have this problem: # LANG=C basename '/test/äaä.txt' äaä.txt So perhaps the problem is more subtle that a simple glibc bug? ------------------------------------------------------------------------ [2012-07-03 15:29:18] pollita@php.net Verified on Debian, but since this is the behavior of the underlying libc implementation, I'm not sure it's PHP's role to fix it. Leaving open for now since we could potentially detect this case and deal with it, but on initial look I'm inclined to push it off on the OS. ------------------------------------------------------------------------ [2012-05-23 08:38:45] thomas dot hebinck at digionline dot de Description: ------------ With the default locale setting "C", basename() drops non-ASCII-chars at the beginning of a filename. Test script: --------------- $path='/test/äaä.txt'; echo $path."\n"; setlocale(LC_ALL,'C'); echo dirname($path).'/'.basename($path)."\n"; setlocale(LC_ALL,'en_US.iso885915'); // bash: locale -a echo dirname($path).'/'.basename($path)."\n"; Expected result: ---------------- /test/äaä.txt /test/äaä.txt /test/äaä.txt Actual result: -------------- /test/äaä.txt /test/aä.txt /test/äaä.txt ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62119&edit=1
