Application and Module Configuration

The \Icinga\Application\Config class is a general purpose service to help you find, load and save configuration data. It is used both by the Icinga 2 Web modules and the framework itself. With INI files as source it enables you to store configuration in a familiar format. Icinga 2 Web defines some configuration files for its own purposes. Please note that both modules and framework keep their main configuration in the INI file called config.ini. Here's some example code:

<?php
use \Icinga\Application\Config as IcingaConfig;

// Retrieve the default timezone using 'Europe/Berlin' in case it is not set
IcingaConfig::app()->global->get('defaultTimezone', 'Europe/Berlin');

// If you don't pass a configuration name to IcingaConfig::app it tries to load values from the
// application's config.ini. For using other files you have to pass this parameter though.
// The following example loads a section from the application's authentication.ini:
IcingaConfig::app('authentication')->get('ldap-authentication');

// If you don't pass a configuration name to IcingaConfig::module it tries to load values from
// the module's config.ini. For using other files you have to pass this parameter though.
// The following example loads values from the example module's extra.ini:
IcingaConfig::module('example', 'extra')->logging->get('enabled', true);
