I just checked this out on PHP Version 5.1.2 and the behavior for me is
the same, so this was not fixed.


reproduced with:
	$tempname = tempnam('', 'foo');
	echo $tempname.'<br>';
	echo realpath($tempname).'<br>';

output in my case:
	\foo5E0.tmp
	d:\foo5E0.tmp

d:\ is not my tempdir

anyway this function behaves inconsisten per default as discribben in
the current online documentaion:

>>Creates a file with a unique filename in the specified directory. If
the directory does not exist, tempnam() may generate a file in the
system's temporary directory, and return the name of that.<<
http://www.php.net/manual/en/function.tempnam.php

so the behavior is correct per definition but useless and i guess not
intended.

Description:
------------
tempnam() returns a temp filename, and creates the file. However, it
creates it on the wrong drive. For example:

$tempname = tempnam('', 'foo');
echo $tempname.'<br>';
echo realpath($tempname).'<br>';

This outputs:

\foo49.tmp
e:\foo49.tmp

Notice the returned filename has no drive letter. The file is created
(to prevent race condition) in C:\ but realpath() resolves that to E:\
(the last drive letter of physical harddrives in this system).

For reference:
 getenv('TMP')    == 'C:\WINDOWS\TEMP'
 getenv('TMPDIR') == ''

Reproduce code:
---------------
$tempname = tempnam('', 'foo');
echo $tempname.'<br>';
echo realpath($tempname).'<br>';



Expected result:
----------------
c:\foo49.tmp
c:\foo49.tmp


Actual result:
--------------
\foo49.tmp
e:\foo49.tmp
