Q: php 5.6.20 - /etc/php5/conf.d directory missing I can't find /etc/php5/conf.d directory in my system. 
Do they change catalog structure ?
I already read /usr/share/doc/php5-common/README.Debian.gz
There is information about linking /etc/php5/$SAPI/conf.d to central directory /etc/php5/conf.d which is not present in my directory

A: If somebody has same problem: 
Default ini file for apc is now located in: /etc/php5/mods-available/ 
Thank you for your time.

A: TL;DR: Look in /etc/php/mods-available dir and use sudo php5enmod
Yes, they have changed the directory structure.
/etc/php5/conf.d
was present in previous Debian releases and has been supported in Debian 7 (wheezy), but, starting with Debian 8 (jessie) you have to use the directory
/etc/php5/mods-available
In Debian 8 you are supposed to use php5enmod/php5dismod utilities to create/remove necessary symlinks in /etc/php5/cli, /etc/php5/apache2, etc.
For example: if in Debian 7 you could create /etc/php5/99-local.ini file and manually add symlinks to this file from /etc/php5/cli, /etc/php5/apache2, etc., now you must:


*

*create /etc/php5/mods-available/local.ini file

*add ; priority=99 line to that file if priority is important to you

*run sudo php5enmod local
Note that php5enmod is not included in normal user's path, so don't expect command-line autocomplete to know this utility.
