Description:
------------
The documentation at http://www.php.net/manual/en/configuration.php#configuration.file states that PHP will look for the configuration file in:

HKEY_LOCAL_MACHINE\SOFTWARE\PHP\IniFilePath\x.y.z

However it seems to be incorrect since the only way I've been able to use it is:

HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x.y.z\IniFilePath



Reproduce code:
---------------
1) Configure PHP for IIS6
2) Add the following registry key in order to load php.ini, according to the documentation for PHP 5.2.0:

HKEY_LOCAL_MACHINE\SOFTWARE\PHP\IniFilePath\5


Expected result:
----------------
Expected PHP to look for php.ini in the registry key: HKEY_LOCAL_MACHINE\SOFTWARE\PHP\IniFilePath\5

Actual result:
--------------
PHP looks for php.ini in the registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\PHP\5\IniFilePath
