Description:
------------
Neither the TEMP or TMP environment variables show up via $_ENV, $_SERVER, getenv() or phpinfo() when accessing scripts via a webserver (Apache 1.3.28).  They're available when executing scripts via the command line (both CGI and CLI).

FYI:
   C:\PROGRA~1>echo %temp%
   C:\TEMP

   C:\PROGRA~1>echo %tmp%
   C:\TEMP

Reproduce code:
---------------
<?php
echo 'TEMP: ' . getenv('TEMP') . "\n";
echo 'temp: ' . getenv('temp') . "\n";
echo 'TMP: ' . getenv('TMP') . "\n";
echo 'tmp: ' . getenv('tmp') . "\n";
?>


Expected result:
----------------
TEMP: C:\TEMP
temp: C:\TEMP
TMP: C:\TEMP
tmp: C:\TEMP

Actual result:
--------------
=== Via web server ===
TEMP: 
temp: 
TMP: 
tmp: 

=== Via command line ===
TEMP: C:\TEMP
temp: C:\TEMP
TMP: C:\TEMP
tmp: C:\TEMP
