Description:
------------
Scandir function wrongly interprets the Turkish "ı" (i without dot) character. It interprets the "ı" as "i".

For the test script, assume there are two directories in a folder:

c:\Music\
 |
 | Aslı
 | Asli



Test script:
---------------
<?php
	$FILES = scandir("C:\\Music\\");
	
	foreach($FILES as $k=>$v)
	{
		if(!mkdir("c:\\TEST\\".$v))
		{
			echo "ERROR for ".$v."\n";
		}
                else
		{
			echo "Folder is created\n";
		}
	}
?>

Expected result:
----------------
Folder is created
Folder is created

Actual result:
--------------
Folder is created

Warning: mkdir(): File exists in C:\testingScandir.php on line 6

I suspect this is an issue with Windows's filesystem case handling and not PHP itself.

Could you try the Command Prompt and see how it responds here?

Apparently, the issue is already with scandir(). var_dump'ing its
result (PHP 7.0.7, German Windows 10):

    array(4) {
      [0]=>
      string(1) "."
      [1]=>
      string(2) ".."
      [2]=>
      string(4) "Asli"
      [3]=>
      string(4) "Asli"
    }

While dir(1) reports:

    14.06.2016  00:33    <DIR>          .
    14.06.2016  00:33    <DIR>          ..
    14.06.2016  00:31    <DIR>          Asli
    14.06.2016  00:31    <DIR>          Aslı
