How to use
1: Introduce smarty’s entry file into index.php: Smarty.class.php

4: The configuration file can be placed in a dedicated file.
Code

<code><span><span><?php </span><span>//引入配置文件</span><span>require</span><span>'smarty/smarty.inc.php'</span>;
   <span>//注册变量</span><span>$name</span>=<span>"eric1122"</span>;
