JFactory/getConfig

Returns a reference to the global configuration object, only creating it if it doesn't already exist. The object returned will be of type JRegistry.

object JRegistry getConfig( $file, $type )

where:

Argument	Data type	Description	Default
$file	string	Path to the configuration file. If null then `path-to-joomla/libraries/joomla/config.php` is assumed.	null
$type	string	Type of configuration file.	'PHP'

This method is used to get access to the global configuration variables. In this example, the site name is retrieved.

$config =& JFactory::getConfig();
echo 'Site name is ' . $config->getValue( 'config.sitename' );
