'.class.php');}$db = new Database();$session=new Session();$smarty = new Smarty();but if i do this it give me the error unable to load the smarty class..function __autoload($class_name) {       require_once( CLASS_LIB./.$class_name . '.class.php');    require_once(DOC_ROOT./libs/Smarty.class.php);}$db = new Database();$session=new Session();$smarty = new Smarty();Warning: require_once(/home/.../classes/Smarty_Internal_TemplateCompilerBase.class.php) [function.require-once]: failed to open stream: No such file or directory in /home/.../includes/init.php Any idea what i am i doing wrong here ? i need to be able to load classes directory automatically but needs to make sure i dont loose smarty path too..
