经典例子:面向对象版图形计算器
在index.php文件中有
echo new Form("index.php");    //Form是一个类,里面有构造方法。
      
echo new Result();   
这是什么意思,new不是创建对象吗?这样输出对象也可以啊。还有创建的对象叫什么名字?
附 :
Form类的构造方法如下:
function __construct() {
        $this->action=$action;
        $this->shape=isset($_GET["action"])?$_GET["action"]:"rect";
    }
        
------解决方案--------------------
echo new Form("index.php");  输出Form的实例化对象,它是一个对象。用echo 输出是会报错的,要用print_r(); 打印才行。
