 New Comment:

In 5.3.5 these functions work as expected even without setlocale().

I tried setlocale() after this problem was found.



I use Apache 2.2.17 (downloaded @ http://www.apachelounge.com/download/)
and php as a module (php5apache2_2.dll)



Just checked CLI - functions work fine

ru_RU would not work reliably before (or now) as it is not a recognized
locale. 

See the links on the setlocale documentation page for a list of the
available 

locale (and cp).



However, the only change in 5.3.6 is that the Locale related APIs are
not per 

thread instead of per process. Making them thread safe and avoid many
possible 

crashes.



Which web server and SAPI do you use? Can you try this code using CLI
(cmd line) 

too?

I had to go back to 5.3.5 where these functions work as expected.

5.3.6 breaks existing and working scripts

Please see the note about Windows and Locale strings at 

http://www.php.net/setlocale



For a portable and reliable locale support, I would suggest to move to
intl, 

http://www.php.net/intl

Description:
------------
At least two string functions fail with cyrillic characters (cp1251) as
of version 5.3.6:

strtolower() and strtoupper().

Test script:
---------------
setlocale(LC_ALL, 'ru_RU');

echo 'strtoupper: '.strtoupper('test тест').'<br>strtolower:
'.strtolower('TEST ТЕСТ');

Expected result:
----------------
strtoupper: TEST ТЕСТ

strtolower: test тест

Actual result:
--------------
strtoupper: TEST тест

strtolower: test ТЕСТ
