OOP PHP价格计算器

Question

代码返回未定义的变量，我认为有些事情是错的，我写的功能，它应该划分$value和$splitfee

class Product { 
    public $name; 
    public $value; 
    public $price; 
    public $splitfee; 

    function split() { 
     $this->value->splitfee = $this->$value/$splitfee; 
    } 
} 

$product_one = new Product(); 
$product_one->name = "potato"; 
$product_one->price = 100; 


$product_two = new Product(); 
$product_two->name = "tomato"; 
$product_two->value = 200; 
$product_two->splitfee = 200; 

$product_three = new Product(); 
$product_three->name = "auto"; 
$product_three->price = 300; 

echo $product_one->name . " is " . $product_one->price . " $" . "<br />"; 
echo $product_two->name . " is " . $product_two->split() . " $" . "<br />"; 

Answer 1

您可以治好你的split()方法，让它返回一个值。这将允许你的内联调用打印内容。

function split() { 
    return $this->value/$this->splitfee; 
} 

然后代码将打印：

potato is 100 $ tomato is 1 $

Answer 2

试试这个，如果我理解正确的逻辑。

class Product { 
    public $name; 
    public $value; 
    public $price; 
    public $splitfee; 

    function split() { 
     return $this->value/$this->splitfee; 
    } 
}
