smarty模板引擎从php中获取数据的方法_PHP

smarty可以分配($smarty->assign)的变量类型：所有php支持的数据类型——基本数据类型、复合数据类型、特殊数据类型（具体见smarty相关手册）。

操作/显示文件：index.php

代码如下:

<?php
//创建smarty对象
require_once("./libs/Smarty.class.php");
$smarty = new Smarty();
$smarty->assign("aa","hello word");//分配字符串
$smarty->assign("bb",123);//分配整型
$smarty->assign("cc",90.8);//分配float型，浮点型
$smarty->assign("dd",true);//分配字符串
//分配数组，数组一般从数据库取出，这里直接给数组
$arr1 = array("北京","上海","广州");//索引数组
$smarty->assign("arr1",$arr1);//分配索引数组

$arr2 = array("city1"=>"北京","city2"=>"上海","city3"=>"广州");//关联数组
$smarty->assign("arr2",$arr2);//分配关联数组

$arr3 = array(array("北京","上海","广州"),array("关羽","张飞","美女"));
$smarty->assign("arr3",$arr3);

$arr4 = array("aa"=>array("北京","上海","广州"),"bb"=>array("关羽","张飞","美女"));
$smarty->assign("arr4",$arr4);

//对象类型
class Master{
public $name;
public $address;
}
$master = new Master();
$master->name="百度";
$master->address = "中关村";
class Dog{
public $name;
public $age;
public $color;
public $arr;
public $master;
function __construct($name,$age,$color,$arr){
$this->name = $name;
$this->age = $age;
$this->color = $color;
$this->arr = $arr;
}
}
$dog = new Dog("小狗",4,"金黄色",$arr2);
$dog->master = $master;
$smarty->assign("dog",$dog);

$smarty->display("index.tpl");
?>

模板文件：index.tpl

代码如下:

smarty变量操作

取字符串：{$aa}

取整数：{$bb}

取浮点型：{$cc}

取布尔值：{$dd}

取数组(索引数组)：{$arr1[0]}--{$arr1[1]}--{$arr1[2]}

取数组(关联数组)：{$arr2.city1}--{$arr2.city2}--{$arr2.city3}

取二组数组(索引，取单个)：{$arr3[0][0]}

取二组数组(索引，遍历全部)：

取二维数组(关联)：{$arr4.aa[2]}

取二维数组(关联、遍历)：

取对象(普通属性)：{$dog->name}

取对象(数组属性)：{$dog->arr.city1}

取对象(对象属性)：{$dog->master->name}
