本文實(shí)例講述了smarty模板引擎從php中獲取數(shù)據(jù)的方法。分享給大家供大家參考。具體如下：
smarty可以分配($smarty->assign)的變量類(lèi)型：所有php支持的數(shù)據(jù)類(lèi)型——基本數(shù)據(jù)類(lèi)型、復(fù)合數(shù)據(jù)類(lèi)型、特殊數(shù)據(jù)類(lèi)型（具體見(jiàn)smarty相關(guān)手冊(cè)）。
操作/顯示文件：index.php
//創(chuàng)建smarty對(duì)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，浮點(diǎn)型
$smarty->assign("dd",true);//分配字符串
//分配數(shù)組，數(shù)組一般從數(shù)據(jù)庫(kù)取出，這里直接給數(shù)組
$arr1 = array("北京","上海","廣州");//索引數(shù)組
$smarty->assign("arr1",$arr1);//分配索引數(shù)組
$arr2 = array("city1"=>"北京","city2"=>"上海","city3"=>"廣州");//關(guān)聯(lián)數(shù)組
$smarty->assign("arr2",$arr2);//分配關(guān)聯(lián)數(shù)組
$arr3 = array(array("北京","上海","廣州"),array("關(guān)羽","張飛","美女"));
$smarty->assign("arr3",$arr3);
$arr4 = array("aa"=>array("北京","上海","廣州"),"bb"=>array("關(guān)羽","張飛","美女"));
$smarty->assign("arr4",$arr4);
//對(duì)象類(lèi)型
class Master{
public $name;
public $address;
}
$master = new Master();
$master->name="百度";
$master->address = "中關(guān)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;
}
}
$dog = new Dog("小狗",4,"金黃色",$arr2);
$dog->master = $master;
$smarty->assign("dog",$dog);
$smarty->display("index.tpl");
?>
