Add an example of setting temp dir on Win8 to solve tmp dir problems on this OS.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. sys_get_temp_dir(); returns "C:\windows"
2. This folder is not writeable by php
3. This causes extensions to malfunction when they need to write temporary files

I would expect the temp folder to be C:\windows\temp or something that I can 
write to.


I am using php_desktop_msie_v10 on Windows 8.


First, I'd like to say that I really like this runtime environment. It's a 
great idea and I've found it very easy to work with. I'm running into this 
problem when trying to use ImageMagick, but I can see it being a problem with 
other extensions as well. I can't find a php.ini directive to change the temp 
folder, so I'm wondering if there's some other way to do it?

On W10, the C:\windows\temp is not writeable either for a non-admin user... So ps-files-cleanup-dir error comes out often... No php putenv or htaccess SetEnv works.
