Q. What are the common methods with which the framework accesses its configuration values and areas?
getStoreConfig(), getStoreConfigFlag(),
$enable = Mage::getStoreConfig(‘socialrecommend/general/enable’,’default’);
$enable = Mage::app()->getStore()-> getConfig(‘socialrecommend/general/enable’);
$enable = Mage::getConfig()-> getNode(‘socialrecommend/general/enable’,’store’,’default’);
$enable = Mage::getConfig()-> getNode(‘stores/default/socialrecommend/general/enable’);
