Description:
------------
The unique file created by tempnam() has the default permissions of 0666 on Windows. But according to documentation http://in.php.net/manual/en/function.tempnam.php, the default permissions are 0600. On Linux tempnam() creates a file with permissions of 0600 as expected i.e according to documentation.

If this is the expected behavior on Windows, please fix the documentation.



Reproduce code:
---------------
<?php
$file_name = tempnam(".", "temp");
printf("%o", fileperms($file_name) );
unlink($file_name);
?>


Expected result:
----------------
100600

Actual result:
--------------
100666

I think it's how chmod on windows works. Try this:

<?php
$file_name = tempnam(".", "temp");
chmod($file_name, 0600);
clearstatcache();
printf("%o", fileperms($file_name) );
?>

I bet you still get 0666..
