arrays - 已编译 tpl 中的 Smarty 和 OOP

Question

$_smarty_tpl->tpl_vars['Variable']->value

我想知道 smarty 如何访问对象。smarty_tpl 是对象，但是编译的 tpl 的代码示例中的属性是什么？是数组tpl_vars还是value两者的混合？

在 php 中，我创建了一个 smarty 对象并将其与方法一起使用（例如分配和显示）。在模板本身（文件 .tpl）中，我不使用 OOP，而是使用类似于 html 的程序样式。

我试着做一个小例子，希望能让你明白这个语法：

//A class that represents a fruit basket, a collection of fruits. Similar to $smarty, which is a collection of variables (among other things)
class FruitBasket
{
    public $basket = array();

    public function foo() {

    }
}
//A class that represents a fruit. It has some properties, like 'name' and 'color' 
class Fruit
{
    public $name = null;
    public $color = null;

    public function __construct($fruit_name) {
        $this->name = $fruit_name;
    }
}

$fruits = array();  //Make an array that will hold various fruits

$fruit = new Fruit('banana');   //Create a fruit
$fruit->color = 'yellow';       //Assign a value to its 'color' property 
$fruits['banana'] = $fruit;     //Assign the fruit to the 'fruits' array

//Make the same steps for 2 more fruits
$fruit = new Fruit('apple');
$fruit->color = 'red';
$fruits['apple'] = $fruit;

$fruit = new Fruit('pear');
$fruit->color = 'green';
$fruits['pear'] = $fruit;

$fruit_basket = new FruitBasket(); //Create a new fruit basket
$fruit_basket->basket = $fruits; //Assign the $fruits array to its 'basket' property

echo $fruit_basket->basket['banana']->color;    //prints 'yellow'
