Description:
------------
On windows, phpinfo() reports things set in the registry even though they are of 
type PHP_INI_PERDIR, so they are in fact not in effect, as documented in 
http://php.net/manual/en/configuration.changes.php. Notably upload_max_filesize 
and post_max_size are values that for example Plesk users keep hitting their heads 
with, as can be seen in these discussions:

http://stackoverflow.com/questions/11730198/php-post-max-size-local-value-
overridden-by-master-value-on-plesk-iis
http://stackoverflow.com/questions/13007906/php-upload-500-internal-server-
error/13008975

Tested on IIS 7.5 system.

Test script:
---------------
Set post_max_size on the registry. Check phpinfo() output.

Expected result:
----------------
post_max_value not having impact on phpinfo() as it is PHP_INI_PERDIR setting and 
has no impact on PHP.

Actual result:
--------------
post_max_value updated as per registry on phpinfo() output, even though not 
effecting PHP.

Thanks for having reported this serious issue!  Unfortunately, the
ticket went unnoticed, and was only fixed later as bug #69134.
