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> </html>
希望本文所述对大家的php程序设计有所帮助。
