------ Solution --------------------
Knowledge of smarty. we recommend that you first read the smarty documentation.
------ Solution --------------------
Smarty
Session_start (); // enable session
Require_once ("common/Common. inc. php"); // contains the configuration file
$ MainTpl = new MySmarty (); // instantiate the class

Then a series of $ mainTpl-> assign () values are passed

Last $ mainTpl-> display('autoweb_index.html '); // template page
Shut down the database.
