本文實例講述了smarty模板引擎從php中獲取數據的方法。分享給大家供大家參考。具體如下：
smarty可以分配($smarty->assign)的變量類型：所有php支持的數據類型——基本數據類型、復合數據類型、特殊數據類型（具體見smarty相關手冊）。
操作/顯示文件：index.php
//創建smarty對象
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，浮點型
$smarty->assign("dd",true);//分配字符串
//分配數組，數組一般從數據庫取出，這里直接給數組
$arr1 = array("北京","上海","廣州");//索引數組
$smarty->assign("arr1",$arr1);//分配索引數組
$arr2 = array("city1"=>"北京","city2"=>"上海","city3"=>"廣州");//關聯數組
$smarty->assign("arr2",$arr2);//分配關聯數組
$arr3 = array(array("北京","上海","廣州"),array("關羽","張飛","美女"));
$smarty->assign("arr3",$arr3);
$arr4 = array("aa"=>array("北京","上海","廣州"),"bb"=>array("關羽","張飛","美女"));
$smarty->assign("arr4",$arr4);
//對象類型
class Master{
public $name;
public $address;
}
$master = new Master();
$master->name="百度";
$master->address = "中關村";
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);
$smarty->display("index.tpl");
?>
模板文件：index.tpl
<h2>smarty變量操作</h2>
<p style="color:green;">取字符串：{$aa}</p>
<p style="color:red;">取整數：{$bb}</p>
<p style="color:blue;">取浮點型：{$cc}</p>
<p style="color:orange;">取布爾值：{$dd}</p>
<p style="color:indigo;">取數組(索引數組)：{$arr1[0]}--{$arr1[1]}--{$arr1[2]}</p>
<p style="color:green;">取數組(關聯數組)：{$arr2.city1}--{$arr2.city2}--{$arr2.city3}</p>
<p style="color:red;">取二組數組(索引，取單個)：{$arr3[0][0]}</p>
<p style="color:red;">取二組數組(索引，遍歷全部)：</p>
<p style="color:blue;">取二維數組(關聯)：{$arr4.aa[2]}</p>
<p style="color:blue;">取二維數組(關聯、遍歷)：</p>
<p style="color:orange;">取對象(普通屬性)：{$dog->name}</p>
<p style="color:orange;">取對象(數組屬性)：{$dog->arr.city1}</p>
<p style="color:orange;">取對象(對象屬性)：{$dog->master->name}</p>

希望本文所述對大家的php程序設計有所幫助。
