$config =& JFactory::getConfig();
$config->setValue('config.custom_var', 'xxx');
// Get the config registry in PHP class format and write it to configuation.php
jimport('joomla.filesystem.file');
if (!JFile::write($fname, $config->toString('PHP', 'config', array('class' => 'JConfig')))) {
die(JText::_('ERRORCONFIGFILE'));
}
