为了避免重复地配置路径,可以在一个smarty文件里配置扩展类,和初始化你的smarty环境。
我们创建一个目录 “/php/includes/guestbook/” 建立一个文件”setup.php”
同样先设置好smarty路径。

/php/includes/guestbook/setup.php

Now for a short word on what Smarty does NOT do. Smarty does not attempt to completely separate logic from the templates. There is no problem with logic in your templates under the condition that this logic is strictly for presentation. A word of advice: keep application logic out of the templates, and presentation logic out of the application. This will most definately keep things manageable and scalable for the foreseeable future.
