Joomla下利用configuration.php存储简单数据

//Getthepathoftheconfigurationfile
$fname=JPATH_CONFIGURATION.DS."configuration.php";
//clearcache
$cache=JFactory::getCache();
$cache->clean();
//Updatethecredentialswiththenewsettings
$config=&JFactory::getConfig();
$config->setValue("config.custom_var","xxx");
//GettheconfigregistryinPHPclassformatandwriteittoconfiguation.php
jimport("joomla.filesystem.file");
if(!JFile::write($fname,$config->toString("PHP","config",array("class"=>"JConfig")))){
die(JText::_("ERRORCONFIGFILE"));
}
