Bug #19795 [Com]: Problems with strnatcmp and strnatcasecmp

Edit report at https://bugs.php.net/bug.php?id=19795&edit=1 ID: 19795 Comment by: redrat at mail dot ru Reported by: doc at nitramlexa dot com Summary: Problems with strnatcmp and strnatcasecmp Status: Closed Type: Bug Package: Strings related Operating System: FreeBSD 4.6 PHP Version: 4.2.2 Block user comment: N Private report: N New Comment: This bug still has place in PHP 5.3.10 for all cyrillic letters (and I think for other non-ASCII letters too). This bug-report was filled almost 10 years ago! Could anybody do something with it? Previous Comments: ------------------------------------------------------------------------ [2004-07-29 10:42:28] larry at kamsha dot ru I have PHP 5.0.0 release with same bug (with cyrillic characters). I've analized sources and found out that comparison is made on "char" values. So all extended characters (with hi-order bit 1) treated as negative. Changing "char" to "unsigned char" would place national characters after english characters (greater in terms of compare), that is correct, but locale-specific collation problem will remain. This is not important for CP1251 or CP866 cyrillic encodings, because theese already have characters sorted by values correctly. But there will be problem for KOI8-R encoding (for which this is not the case). The problem can be easily solved by using "strcoll" (in place of dumb value compare), I guess. ------------------------------------------------------------------------ [2004-07-16 04:32:57] mbp at sourcefrog dot net This bug does seem to still be present in php5 CVS. The comparison is simply by byte values, not taking character set or locale into account. ------------------------------------------------------------------------ [2004-06-28 14:55:26] mikael at chl dot chalmers dot se This bug seems to have popped back again in version 4.3.7 When using setlocale(LC_ALL, 'sv_SE') the national chars åäö get sorted before other international chars, they should appear at the bottom. ------------------------------------------------------------------------ [2003-04-16 16:11:22] moriyoshi@php.net This bug has been fixed in CVS. In case this was a PHP problem, snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. In case this was a documentation problem, the fix will show up soon at http://www.php.net/manual/. In case this was a PHP.net website problem, the change will show up on the PHP.net site and on the mirror sites in short time. Thank you for the report, and for helping us make PHP better. ------------------------------------------------------------------------ [2003-01-27 16:11:34] kamikaze at yifan dot net I have the same problem, with æøå. strtoupper() does, for example, not uppercase those letters.
