Description:
------------
php.ini on Windows (default, production):

; Directory in which the loadable extensions (modules) reside.
; http://php.net/extension-dir
;extension_dir = "./"
; On windows:
;extension_dir = "ext"

The issue is that default doesnt work on Windows. You have to uncomment extension_dir = "ext", otherwise PHP wont run if you uncomment extensions.



Expected result:
----------------
Windows extensions work right away

On Windows, the default value is actually the value of
PHP_EXTENSION_DIR (which is basically undocumented[1]).  That value
is actually PHP_PREFIX."\\ext", and the prefix can be configured
(--with-prefix) during build time.  The official binaries use the
default (C:\php for non debug builds).

I think this is basically the same on other operating systems.
Not sure what to do about php.ini.

Looks like we both hit edit at the same time :)

I had to uncomment it first to reach that extensions work at all and its always in ext folder on windows anyway. So I'd say its a bug and default value should be "ext" and not whatever it is.

The relative path ext doesn't work for all SAPIs, e.g.
Apache2Handler needs an absolute path.

PHP_EXTENSION_DIR is now documented[1].  I think we should leave
php.ini alone.
