Reported By: spud at nothingness dot org
Status: No Feedback
Bug Type: Scripting Engine problem
Operating System: Linux (RedHat 7.2)
PHP Version: 5CVS, 4CVS (2005-10-04)
Assigned To: andrei
New Comment:
class_exists() function uses zend_str_tolower(). zend_str_tolower()
uses
zend_tolower(). zend_tolower() uses _tolower_l() on Windows and
tolower() on other oses. _tolower_l() is not locale aware. tolower() is
LC_CTYPE aware.
Turkish language can trigger some i18n programming errors in case
insensitive comparison functions, because small latin i is not equal to
capital latin i in Turkish language. Azerbaijani (az) and Kurdish (ku)
locales use Turkish language rules on Linux.
P.S. According to msdn documentation _tolower_l() is not meant to be
called directly and is provided for internal use by _totlower_l

I can confirm that this bug is still there... I'm testing with snapshot
php5.2-200706031230 and get the following...
Instantiating an infoBlob with a lowercase i<br>Foo<br>Instantiating an
InfoBlob with an uppercase I<br>
Fatal error: Class 'InfoBlob' not found in
/root/php5.2-200706031230/test.php on line 18
Another simple script I have discovered that shows the same problem
is...
<?php
echo setlocale(LC_ALL, "tr_TR.utf8")."\n";
foreach(get_declared_classes() as $class)
{
if(!class_exists($class))
echo "$class No Longer Exists!\n";
}
?>
For this program I get the following output...
[EMAIL PROTECTED] php5.2-200706031230]# sapi/cli/php ~/test2.php
tr_TR.utf8

This does not just occur with tr_TR.utf8 it also occurs with the
following locales... tr_CY.utf8, ku_TR.utf8 and az_AZ.utf8.
Thanks
