Answer 1

Your Filepath is probably incorrect

Check the Apache error log in

/var/log/apache2/error.log

if the called path or filename does match your real path in e.g.

/usr/lib/php/20151012/php_curl.so

In my case it's been the same path, but "the php_" was missing

/usr/lib/php/20151012/curl.so

So I changed the path / filename accordingly in

/etc/php/7.0/cli/conf.d/20-curl.ini 

from

extension=php_curl.so

into

extension=curl.so
