New Comment:
Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same.
Thank you for your interest in PHP.
Same as bug #35050 (read the last comment..)

Description:
------------
PHP zend_str_tolower() is locale insensitive on Windows and locale
(LC_CTYPE) sensitive on other platforms. It causes case sensitivity
problems in class and method names with Turkish locale on Linux, because
Turkish locale has case sensitivity rules that differ from US English
rules. Programmers make mistake by assuming that Latin small letter i is
always equal to Latin capital letter i.
Issue can be fixed by writing tolower() function alternative that is
not LC_CTYPE sensitive. My tests show that if zend_str_tolower() is
modified to do locale insensitive case conversion, basic PHP install
passes 'make test' without any additional issues and Zend/bench.php does
not show performance decrease.
My code modifications are based on program licensed under GPL. locale
insensitive tolower() takes only 5 lines in C. I can post link to patch,
if you can use GPL code. If you can't do that, I can explain your
programmers how locale insensitive tolower() works and you can write own
function.
I know about 40086, 35583, 35050 and 18556 bug reports, but these bug
reports are closed and it looks strange, if you don't fix the issue when
interpreter works correctly on Windows and BSD and fix takes less than
10 lines.
Tested PHP 5.2-200709030430 and PHP6-200709030430 (unicode.semantics =
off) snapshot. PHP6-200709030430 with unicode.semantics=on is not
affected.
If you have other open bug report on this issue, please give its
number.
Reproduce code:
---------------
class TestIt { }
class testclass2 {
function TestItToo() {}
}
var_dump(setlocale(LC_ALL,'tr_TR.UTF-8'));
var_dump(class_exists('TestIt'));
$TestObj = new testclass2();
var_dump(method_exists($TestObj,'TestItToo'));
Expected result:
----------------
string(11) "tr_TR.UTF-8"
bool(true)
bool(true)
Actual result:
--------------
string(11) "tr_TR.UTF-8"
bool(false)
bool(false)
