 Mage::getBaseDir()  //output : /var/www/html/magento
Mage::getBaseDir('app')  //output : /var/www/html/magento/app
Mage::getBaseDir('media') //output : /var/www/html/magento/media
Mage::getBaseDir(‘design’) => Get design directory path
Mage::getBaseDir(‘code’) => Gives code directory file path
Mage::getBaseDir(‘lib’) => Gives lib directory file path
Mage::getBaseDir(‘skin’) => Gives skin directory file path
Mage::getBaseDir(‘var’) => Gives var directory file path
Mage::getBaseDir(‘cache’) => Gives cache directory file path
Mage::getBaseDir(‘log’) => Gives log directory file path 

 
 
 
2) Get Base URL
 Mage::getBaseUrl() => Get base url path e.g. http://yourwebsite.com/
 Mage::getBaseUrl('media') => Get MEDIA folder path e.g. http://yourwebsite.com/media/
 Mage::getBaseUrl('js') => Get JS folder path e.g. http://yourwebsite.com/js/
 Mage::getBaseUrl('skin') => Get SKIN folder path e.g. http://yourwebsite.com/skin/

 3) Get Current URL
Mage::helper('core/url')->getCurrentUrl();


4) Get Home URL
Mage::helper('core/url')->getHomeUrl();

5) Create module your
Mage::getUrl('module/controller/action');

6)  Get secure URL(To get secure URL you just need to add one more parameter as bellow)
Mage::getUrl('',array('_secure'=>true))
Mage::getUrl('module/controller/action',array('_secure'=>true))
