Config
Global Configuration
Accessing the global site configuration:
$jconfig = JFactory::getConfig();
Retrieving a value from the configuration:
echo $config->getValue('config.sitename');
Component Configuration
Although rarer than accessing the global site configuration, sometimes it is necessary to access component-specific configurations. This can be done as follows:
$config = JComponentHelper::getParams('com_mycomponent');
Retrieving a value from the configuration:
echo $config->get('paramName');
