Bug #18556 [Csd]: Setting locale to 'tr_TR' lowercases class names

Edit report at https://bugs.php.net/bug.php?id=18556&edit=1 ID: 18556 Updated by: nikic@php.net Reported by: spud at nothingness dot org Summary: Setting locale to 'tr_TR' lowercases class names Status: Closed Type: Bug Package: Scripting Engine problem Operating System: Linux (RedHat 7.2) PHP Version: 5CVS, 4CVS (2005-10-04) Assigned To: stas Block user comment: N Private report: N New Comment: @necmettin: Per the previous comments of stas and jpauli, this issue has been fixed in PHP 5.5 and above only, so this issue persisting on 5.4 is to be expected. Previous Comments: ------------------------------------------------------------------------ [2016-04-15 23:37:39] necmettin dot begiter at gmail dot com @nikic sorry, php version is 5.4.27 Yes, when I do not load Twig extension, this specific error goes away (only things dependent on Twig break, which has nothing to do with this bug). If these change anything: PHP is running in Apache as FastCGI; Zend Engine 2.4.0, ionCube loader v4.4.1. I can also provide a phpinfo() url if needed. Also note that the initial error reproduction code given by @spud @2002 does not reproduce. But the <?php echo setlocale(LC_ALL, "tr_TR.utf8")."\n"; foreach(get_declared_classes() as $class) { if(!class_exists($class)) echo "$class No Longer Exists!\n"; } ?> code reproduces, and I get tr_TR.utf8 DateInterval No Longer Exists!

Does this only happen if the twig extension is loaded? @marcin: Do you see this issue with the reproduce script from the initial report, or with some other code? ------------------------------------------------------------------------ [2016-04-15 22:56:45] necmettin dot begiter at gmail dot com I'm having a problem that I believe is a side-effect of this issue. I'm using the Twig extension in a project, and it uses the IteratorAggregate interface. When the locale is tr_TR, I get Fatal error: Interface 'IteratorAggregate' not found in .. When I do setlocale('en_US.UTF-8') or 'es_ES.UTF-8', everything works fine. I can provide the PHP compilation command line but the IteratorAggregate interface is built-in, so I assume it would be practically impossible to remove the interface during the compilation process. ------------------------------------------------------------------------ [2016-03-11 12:01:12] marcin dot filip at gmail dot com Hi this bug is still exists in new php versions. We have same problem with php version 5.6.18 and from your comments should be fixed in 5.5 but it isn't. Question is why change locale is affecting interpreter matching method which should be independend from locale. And stable in any case. So some one can tell me when this problem will be solved because for multi language solution using locale as language settings and in some cases use the data formatting unique by country. Or maybe you can provide some information how to omit that error or some fix for that (maybe patch) ------------------------------------------------------------------------ [2012-12-04 17:32:06] jpauli@php.net So, to sum things up : The bugs has only been fixed in 5.5 branch. It mainly uses a char map to lower characters instead of relying on locale-aware (possibly buggy versions) system's libc. You can find details with internal zend functions affected directly by reading the source, here : http://lxr.php.net/xref/PHP_TRUNK/Zend/zend_operators.c#45 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
