smarty模板引擎从php中获取数据的方法

本文实例讲述了smarty模板引擎从php中获取数据的方法。分享给大家供大家参考。具体如下:

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

<?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

<html>

<h2>smarty变量操作</h2>

<p style="color:green;">取字符串:{$aa}</p>

<p style="color:red;">取整数:{$bb}</p>

<p style="color:blue;">取浮点型:{$cc}</p>

<p style="color:orange;">取布尔值:{$dd}</p>

<p style="color:indigo;">取数组(索引数组):{$arr1[0]}--{$arr1[1]}--{$arr1[2]}</p>

<p style="color:green;">取数组(关联数组):{$arr2.city1}--{$arr2.city2}--{$arr2.city3}</p>

<p style="color:red;">取二组数组(索引,取单个):{$arr3[0][0]}</p>

<p style="color:red;">取二组数组(索引,遍历全部):</p>

<p style="color:blue;">取二维数组(关联):{$arr4.aa[2]}</p>

<p style="color:blue;">取二维数组(关联、遍历):</p>

<p style="color:orange;">取对象(普通属性):{$dog->name}</p>

<p style="color:orange;">取对象(数组属性):{$dog->arr.city1}</p>

<p style="color:orange;">取对象(对象属性):{$dog->master->name}</p>
