Description:
------------
If there is a file or directory named php.ini in the current directory and you start php-fpm from within this directory, phpinfo() output shows, that php-fpm is trying to use this file/directory as main configuration file for all it's children.

The case with such php.ini being a file seems to be undocumented and unwanted behavior because by default [prefix]/lib/php.ini should be used.

The case with php.ini being a directory leads to all php settings to be silently reverted to their defaults. No error message is shown about that php.ini is not a file or does not exist or whatever.

Test script:
---------------
cd ~
mkdir php.ini
php-fpm

After that open a page, containing phpinfo(); line and check php.ini settings section.
