The site settings are located in the config namespace within the registry. A table
describing the values we expect to be present in the config namespace can be found
in the Appendix.
Saving and Loading Registry Values
A powerful feature of JRegistry objects is the capacity to save and load data. The
class supports two different format types, run-time data and files. Run-time data are
arrays and objects. File data can come from files in INI, PHP, and XML format.
In the previous three chapters, we have discussed the handling of extension
settings. In addition to those methods, we can use the JRegistry class. This example
demonstrates how to load an INI file into the myExtension namespace:
$file = JPATH_COMPONENT.DS.'myExtension.ini';
$registry =& JFactory::getConfig();
$registry->loadFile($file, 'INI', 'myExtension');
If we make changes to the myExtension namespace, we can save the changes back to
our INI file:
// import JFile
jimport('joomla.filesyste.file');
// prepare for save
$file = JPATH_COMPONENT.
