What is the/a correct/proper directory for PHP 7 modules INI files?

Question

Thanks to the issue with enabling/disabling of PHP modules with phpdismod I checked out the structure of the PHP config files on my Ubuntu VM and noticed, that there are two folders for the config includes: /etc/php/mods-available/ and /etc/php/7.0/mods-available/. (I'm pretty sure, that I didn't created them or even one of them manually.)

Which is the actually correct folder for the PHP 7 INI config includes? /etc/php/7.0/mods-available?

^{Additionally: Does it matter in general, where the PHP config includes are stored? Can there be any side effects, if I now merge the both directories (e.g. moving all files from /etc/php/mods-available/ to /etc/php/7.0/mods-available/).}

It depends on whichever php version you're using. Check 'php --version' and `php -i | grep ini` to see your version and where it's set to check for the ini's. There could be an issue if you copy one to the other if they aren't for the same version of PHP. — aynber, Jul 01 '16 at 15:45
@aynber Thanks for your comment! I'm using `v7` (it's the only PHP instance on the machine). So, you mean `/etc/php/mods-available/` is the folder for the modules shared by different PHP versions? — automatix, Jul 01 '16 at 15:50
In some of the systems I've used, that was the folder used by PHP5. You can try moving some of the files, but you might have issues upgrading in the future, since it expects the folders to be in those particular folders. — aynber, Jul 01 '16 at 15:57
I'm wondering, that the INI includes are created in two folders and in the same time `phpdismod` works only of of them. — automatix, Jul 01 '16 at 16:00
