Bug #17642 Updated: setting certain locales undefines defines

ID: 17642 Updated by: ilia@prohost.org Reported By: ilia@prohost.org Status: Open Bug Type: Scripting Engine problem Operating System: Linux 2.4.18 PHP Version: 4.2.1 New Comment: I've looked the Zend constants code and it appears the code ALWAYS lowercases the name of the define (not done for variables). To lowercase the define name, C's tolower() function is used, which obides by locale settings, since I is not avaliable it is left as is accoring to the tolower()'s man page. The solution which appears to work, seems to be the removal of zend_str_tolower(lookup_name, name_len); inside ZEND_API int zend_get_constant function and removal of end_str_tolower(lowercase_name, c->name_len); inside ZEND_API int zend_register_constant Previous Comments: ------------------------------------------------------------------------ [2002-06-07 11:28:46] ilia@prohost.org Yeah, that does appear to be the problem, any define containing the letter 'I' gets broken after the local is exported. Interestingly enough, if I move the define below the setlocale() lin,e it begins to work fine. Also, this does not seem to be a problem for variable names as they are unaffected by change in locale. ------------------------------------------------------------------------ [2002-06-07 11:14:40] derick@php.net This is because the 'I' doesn't exist in tr_TR.

Here is an example script <? define('__REQUEST_TIMESTAMP__', time()); echo "BEFORE: ".__REQUEST_TIMESTAMP__."<br>\n"; setlocale(LC_ALL, 'tr_TR'); echo "AFTER: ".__REQUEST_TIMESTAMP__."<br>\n"; ?> Results in the following output: BEFORE: 1023461965 Notice: Use of undefined constant __REQUEST_TIMESTAMP__ - assumed '__REQUEST_TIMESTAMP__' in /home/forum/test.php on line 12 AFTER: __REQUEST_TIMESTAMP__ On the otherhand using any other locale, such as de_DE or pl_PL seems to work fine and does not undefine the define. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=17642&edit=1
