The allocation data type of smarty template engine, the smarty template data type

The example in this article describes the usage of allocation data type of smarty template engine. Share it with everyone for your reference. The specific analysis is as follows:

1. Distribute basic data

//分配基本数据
$smarty->assign("str","hello smarty!");
$smarty->assign("int",143);
$smarty->assign("double",12.1344);
$smarty->assign("bool",true);
$smarty->assign("bool2",false); 
字符串类型：<{$str}> <br/>
整型：<{$int}> <br/>
浮点型：<{$double}> <br/>
布尔类型真：<{$bool}> <br/>
布尔类型假：<{$bool2}> <br/> 

The browser displays the result:

1 means true, 0 means false. When false, it is null and nothing is displayed.

2. Distribute array of composite data

//索引数组 
$res=array('上海','北京','深圳');
$smarty->assign("arr",$res);
//关联数组
$res2=array('city1'=>'北京','city2'=>'广州','city3'=>'湖南');
$smarty->assign("arr2",$res2); 
//索引二维数组
$res3 = array( 
  array('潇晓','常山','吴蓓'),array('珊珊','常明')
); 
$smarty->assign("arr3",$res3); 
//关联二维数组 
$res4 = array( 
  array('id'=>'001','name'=>'张三','email'=>'zhangsan@1163.com'),
  array('url'=>'http://www.baidu.com','age'=>'28')
); 
$smarty->assign("arr4",$res4); 
//关联二维数组2 
$res5=array( 
  'emp1'=>array('id'=>'001','name'=>'张三','email'=>'zhangsan@1163.com'),
  'emp2'=>array('url'=>'http://www.baidu.com','age'=>'28')
); 
$smarty->assign("arr5",$res5);

Template file

索引数组：元素1:<{$arr[0]}>,元素2:<{$arr[1]}>,元素3:<{$arr[2]}> <br/> 
关联数组取法1(不推荐)：元素1:<{$arr2['city1']}>,元素2:<{$arr2['city2']}>,元素3:<{$arr2['city3']}> <br/> 
关联数组取法2(推荐)：元素1:<{$arr2.city1}>,元素2:<{$arr2.city2}>,元素3:<{$arr2.city3}> <br/> 
二维索引数组： 
元素1:<{$arr3[0][0]}>, 
元素2:<{$arr3[0][1]}>, 
元素3:<{$arr3[0][2]}>, 
元素4:<{$arr3[1][0]}>, 
元素5:<{$arr3[1][1]}> <br/> 
关联二维数组形式1： 
id-<{$arr4[0].id}>, 
name-<{$arr4[0].name}>, 
email-<{$arr4[0].email}>, 
url-<{$arr4[1].url}>, 
age-<{$arr4[1].age}> <br/> 
关联二维数组形式2： 
id-<{$arr5.emp1.id}>, 
name-<{$arr5.emp1.name}>, 
email-<{$arr5.emp1.email}>, 
url-<{$arr5.emp2.url}>, 
age-<{$arr5.emp2.age}><br/>

The browser displays the result:

3. Allocate composite data objects

class Master{ 
  var $name; 
  var $age; 
  function __construct($name,$age){ 
    $this->name=$name; 
    $this->age=$age; 
  } 
} 
class Dog{ 
var $name; 
var $age; 
var $color; 
var $arr; 
var $master; 
function __construct($name,$age,$color,$arr6,$master){ 
  $this->name=$name; 
  $this->age=$age; 
  $this->color=$color; 
  $this->arr=$arr6; 
  $this->master=$master; 
  } 
} 
$arr6=array('001','002','003'); 
$master = new Master('小明',22); 
$dog1 = new Dog('小白',1,'white',$arr6,$master); 
$smarty->assign("dog",$dog1);

Template file

对象：<br/> 
//基本属性 
name-<{$dog->name}>, 
age-<{$dog->age}>, 
color-<{$dog->color}> <br/> 
//数组属性 
arr-<{$dog->arr[0]}>, 
arr-<{$dog->arr[1]}>, 
arr-<{$dog->arr[2]}> <br/> 
//对象属性 
object-<{$dog->master->name}>, 
object-<{$dog->master->age}> <br/> 

Browser displays results
