二 ，Smarty模板技术/引擎——变量操作(1)

1，基本变量

$smarty->assign('data1',3);
$smarty->assign('data2',3.45);
$smarty->assign('data3','fffff');
$smarty->assign('data41',true);
$smarty->assign('data42',false);

整数：<{ $data1 }><br/>
小数：<{ $data2 }><br/>
字符串：<{ $data3 }><br/>
布尔型true：<{ $data41 }><br/>
布尔型false：<{ $data42 }><br/>

输出如下：

2，数组

//一维索引数组
$arr1=array("北京","上海","天津");
$smarty->assign('arr1',$arr1);
 
//一维关联数组
$arr2 = array("city1"=>"北京", "city2"=>"上海", "city3"=>"天津");
$smarty->assign('arr2',$arr2);
 
//二维索引数组
$arr3 = array(array("北京","上海","天津"),array("小倩","彩臣","老妖"));
$smarty->assign('arr3',$arr3);
 
//二维关联数组
$arr4 = array(
    array("id"=>"001","name"=>"liuhuayong","age"=>10),
    array("id"=>"002","name"=>"niexiaoqian","age"=>20),
    array("id"=>"003","name"=>"heishanlaoyao","age"=>30)
);
$smarty->assign('arr4',$arr4);
 
//二维关联数组
$arr5 = array(
    'emp1'=>array("id"=>"001","name"=>"liuhuayong","age"=>10),
    'emp2'=>array("id"=>"002","name"=>"niexiaoqian","age"=>20),
    'emp3'=>array("id"=>"003","name"=>"heishanlaoyao","age"=>30)
);
$smarty->assign('arr5',$arr5);

一维索引数组：<{ $arr1[0] }>||<{ $arr1[1] }>||<{ $arr1[2] }><br/>
一维关联数组：<{ $arr2.city1 }>||<{ $arr2.city2 }>||<{ $arr2.city3 }><br/>
二维索引数组：<{ $arr3[1][1] }>||<{ $arr3[1][2] }><br/>
二维关联数组：<{ $arr4[1].id }>||<{ $arr4[1].name }>||<{ $arr4[1].age }><br/>
二维关联数组：<{ $arr5.emp1.id }>||<{ $arr5.emp1.name }>||<{ $arr5.emp1.age }><br/>

输出：

3，对象

class dog{
    public $name;
    public $age;
    public function __construct($name,$age){
        $this->name = $name;
        $this->age = $age;
    }
}
$dog = new dog('花花',4);
$smarty->assign('dog',$dog);

对象：<{ $dog->name }>||<{ $dog->age }>
