Description:
------------
When using per-directory or per-host php.ini files, none of the master file's configuration settings are read (i.e. from "C:\Server\PHP\PHP5\php.ini").  PHP requires that all settings that are needed to have a value be set per-directory/per-host.  In my mind, PHP should load the default configuration file (i.e. C:\Server\PHP\PHP5\php.ini) as well as the per-directory/per-host config file (i.e. C:\Server\Sites\Framework\php.ini), load the directives from the master file, and then override/replace the values for those directives from the child config file.

Reproduce code:
---------------
master php.ini:
cgi.force_redirect = 0
doc_root =
extension_dir = "C:/Server/PHP/PHP5/ext"

Host php.ini:
doc_root = "C:\Server\Sites\Framework"

Expected result:
----------------
when phpinfo() executed:
System Information
---------------------------------------------------------------------
Loaded Configuration File(s): C:\Server\Sites\Framework\php.ini; C:\Server\PHP\PHP5\php.ini

Directive Values
---------------------------------------------------------------------
cgi.force_redirect: Local: 0; Master: 0;
doc_root: Local: C:\Server\Sites\Framework; Master: no value;
extension_dir: Local: C:/Server/PHP/PHP5/ext; Master: C:/Server/PHP/PHP5/ext


Actual result:
--------------
when phpinfo() executed:
System Information
---------------------------------------------------------------------
Loaded Configuration File: C:\Server\Sites\Framework\php.ini

Directive Values
---------------------------------------------------------------------
cgi.force_redirect: Local: no value; Master: no value
doc_root: Local: C:\Server\Sites\Framework; Master: C:\Server\Sites\Framework
extension_dir: Local: no value; Master: no value
