Security & setup warnings > Which php.ini to edit?

[ghost]

Ubuntu 16.04, php7, apache
I got this warning after updating to 12 (from 11.3 - everything went well, I lost the T-shirt).
But I got this waring from NextCloud installation:
Security & setup warnings

It's important for the security and performance of your instance that everything is configured correctly. To help you with that we are doing some automatic checks. Please see the Tips & Ticks section and the documentation for more information.

    The PHP Opcache is not properly configured. For better performance we recommend ↗ to use following settings in the php.ini:

    opcache.enable=1
    opcache.enable_cli=1
    opcache.interned_strings_buffer=8
    opcache.max_accelerated_files=10000
    opcache.memory_consumption=128
    opcache.save_comments=1
    opcache.revalidate_freq=1

Please double check the installation guides ↗, and check for any errors or warnings in the log.

The question is, which php.ini is this refering to?
/etc/php/7.0/cli/php/ini?
or
/etc/php/7.0/apache2/php.ini?

I guess it's /etc/php/7.0/apache2/php.ini? should be edited but maybe could be written to the instructions

/etc/php/7.0/apache2/php.ini should be fine when you're using apache2 as your webserver.

But it should be possible to dynamically show the path to the correct PHP.ini to edit using function.php-ini-loaded-file.
