title: What are the .ini files in /etc/php5/conf.d folder for?
body: <p>I get that the .ini files in <code>/etc/php5/cli</code> have to do with CLI usage of PHP, the files in <code>/etc/php5/fpm</code> are about FastCGI/FPM aspect of PHP, but what about the .ini files located in <code>/etc/php5/conf.d</code>?</p>
