Accessing Global Configuration Information in Joomla

Like user information, accessing global configuration of Joomla (like site name, from name) is a very simple process. You can use getConfig() method of Factory class in any part of the Joomla extension or template.

$config = Factory::getConfig();

For example, site name stored in global configuration can be retrieved as

$config->get('sitename')

Similarly, from name can be retrieved as

$config->get('fromname')

You can check configuration.php file stored in root Joomla folder for all the global information that can be accessed in this way.
