smarty高级特性中对象的使用：
具体见下例：
<?php
include_once('smarty.inc.php');
class Dog{
public $name;
public function sayHello(){
echo 'hello';
}
}
$dog1=new Dog();
$dog1->name="first dog";
$smarty->assign("dog",$dog1);
$smarty->display('test.tpl');
?>
test.tpl
属性调用：{$dog->name}<br />
方法调用：{$dog->sayHello()}
输出显示：
first dog
hello
