Nginx editing php.ini changes no reflecting

Solution 1:

You need to restart it. I use 7.0 so change the 7.0 to your version.

sudo systemctl restart php7.0-fpm

Solution 2:

Have you tried to put your php.ini under /etc/php5/fpm/php.ini? This is normally the default location that php reads from, if I understand php5-fpm correctly.
