Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
This is not the same as #18556 as you are manually using "strtoupper", which is
locale-dependent, so it does what you asked it to do - provides the locale-dependent uppercase
rendering of "production". Unfortunately, in tr_TR the uppercase of "production"
is "PRODUCTÄ°ON" and not "PRODUCTION". If you must use this locale, I'd
suggest using mb_strtoupper or mb_convert_case.

PHP's strtolower() has always been locale aware and works the same in 5.4 and 5.5.
Did I miss something ?

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
------------------------------------------------------------------------
