php - 在子 PHP 之后自动调用父构造函数

Question

我尝试使用父类的名称(如构造函数)并为我部分工作。

第一次调用

"DarthVader method"

像构造函数但从不调用

"LukeSkywalker constructor"..

有人知道怎么做吗？

example:

达斯.php

class DarthVader{
    public function DarthVader(){
        echo "-- Obi-Wan never told you what happened to your father.\n";
    }
    public function reponse(){
        echo "-- No. I am your father\n";
    }
}

卢克.php

include("Darth.php")

class LukeSkywalker extends DarthVader{
 public function __constructor(){
        echo "- He told me enough! He told me you killed him!\n"
        $this->response();
    }
}

Expected result:

• 欧比旺从未告诉过你父亲的遭遇。

• 他告诉我够多了!他告诉我你杀了他!

• 没有。我是你爸爸

我真的希望它自动如此。

根据文档:http://php.net/manual/en/language.oop5.decon.php

Note: Parent constructors are not called implicitly if the child class defines a constructor. In order to run a parent constructor, a call to parent::__construct() within the child constructor is required. If the child does not define a constructor then it may be inherited from the parent class just like a normal class method (if it was not declared as private).
