Joomla下利用configuration.php存储简单数据

　　// Get the path of the configuration file

　　$fname = JPATH_CONFIGURATION.DS.'configuration.php';

　　// clear cache

　　$cache = JFactory::getCache();

　　$cache->clean();

　　// Update the credentials with the new settings

　　$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'));

　　}

　　global $mainframe;

　　$mainframe->getCfg('custom_var');
