The allocation data type of smarty template engine

This article mainly introduces the allocation data type of smarty template engine, and analyzes the usage skills of smarty template engine data type with examples. For reference value, friends in need can refer to it

The example in this article describes the usage of allocated data types by 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}>

整型：<{$int}>

浮点型：<{$double}>

布尔类型真：<{$bool}>

布尔类型假：<{$bool2}>

//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);

//Assign basic data $smarty->assign("str","hello smarty!"); $smarty->assign("int",143); $smarty->assign("double",12.1344); $smarty->assign("bool",true); $smarty->assign("bool2",false); String type: <{$str}>
Integer type: <{$int}>
Floating point type: <{$double}>
Boolean type true: <{$bool}>
Boolean type false: <{$bool2}>

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：元素1:<{$arr[0]}>,元素2:<{$arr[1]}>,元素3:<{$arr[2]}>

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']}>

关联数组取法2(推荐)：元素1:<{$arr2.city1}>,元素2:<{$arr2.city2}>,元素3:<{$arr2.city3}>

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]}>

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}>

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}>
