Summary: Setting locale to 'tr_TR' lowercases parts of
constants
Status: Open
Type: Bug
Package: Scripting Engine problem
Operating System: CentOS 6
PHP Version: 5.5.6

The bug doesn't exist in php 5.4.31. So it could be introduced in php 5.5. The nasty part of
this bug is that a locale change would affect how php handles some "English" letter.

I think this bug also affects preg_match() function while using the case insensitive match modifier.
Seems only letter 'i' has the problem. See example below:
<?php
setlocale(LC_ALL, 'tr_TR.UTF-8');
var_dump(preg_match('/I/i', 'production')); // output: no match found (WRONG)
var_dump(preg_match('/O/i', 'production')); // output: one match found
(correct)

In short:
setlocale(LC_ALL, 'tr_TR.UTF-8');
echo strtoupper('production');
Result: "PRODUCTiON" with wrong "i"

Description:
------------
Hi. The (same?) bug was closed long time before here: https://bugs.php.net/bug.php?id=18556
Now its back in php 5.5.6.
Write
setlocale(LC_ALL, 'tr_TR.UTF-8');
I get:
constant(): Couldn't find constant test::PRODUCTiON
and complete page is broken.
See "i" in "PRODUCTiON". Change 'tr_TR.UTF-8' to another string like
'en_US.UTF-8' now its working fine.
Test script:
---------------
class test {
const PRODUCTION = 20;
public static $environment = 10;
}
test::$environment = constant('test::'.strtoupper('production'));
echo (test::$environment);
Expected result:
----------------
20
Actual result:
--------------
Error message: constant(): Couldn't find constant test::PRODUCTiON
------------------------------------------------------------------------
