4- a main configuration file, usually found under `/etc/php5/php.ini`; some distributions provide different configuration environments, e.g.
5 - `/etc/php5/php.ini` - used when running console scripts
6 - `/etc/php5/apache2/php.ini` - used when a client requests PHP resources from Apache
7 - `/etc/php5/php-fpm.conf` - used when PHP requests are proxied to PHP-FPM
8- additional configuration files/entries, depending on the installed/enabled extensions:
9 - `/etc/php/conf.d/xdebug.ini`

11### Locate .ini files
12#### Console environment
13```bash
14$ php --ini
15Configuration File (php.ini) Path: /etc/php
16Loaded Configuration File: /etc/php/php.ini
17Scan for additional .ini files in: /etc/php/conf.d
18Additional .ini files parsed: /etc/php/conf.d/xdebug.ini

21#### Server environment
22- create a `phpinfo.php` script located in a path supported by the web server, e.g.
23 - Apache (with user dirs enabled): `/home/myself/public_html/phpinfo.php`
24 - `/var/www/test/phpinfo.php`
25- make sure the script is readable by the web server user/group (usually, `www`, `www-data` or `httpd`)
26- access the script from a web browser
27- look at the _Loaded Configuration File_ and _Scan this dir for additional .ini files_ entries
