How are additional ini files added to php-fpm+nginx?

Question

PHP

Essence of the question: I downloaded the VVV assembly , but the php.ini parameters stubbornly do not change the configuration regarding error_reporting errors. There is no forced directive in /etc/php5/fpm/php.ini nor /etc/php5/fpm/conf.d/php-custom.ini in /etc/php5/fpm/php-fpm.conf, phpinfo shows that when change in php-custom.ini, the master value error_reporting changes to the one I need, but the local value error_reporting does not. Where could be the problem?
[SOLUTION] Everything is trite in the wp-config of a specific host, in my case wordpress-default is enabled debug mode by default the constant WP_DEBUG true if it is disabled, control is transferred to the config /etc/php5/fpm/conf.d/php-custom.ini
At the same time tell me where adding additional ini files to nginx? Or is everything in the modular installation in the kernel prescribed?
these questions are open but the problem is generally solved

Answer 1

nginx has the same relationship to php-fpm settings as amarok or firefox has to them. That is, none.
See what files are included from your config, read the config carefully for inclusions.
