php - PHP OOP How to call an object's parent method from the object itself?

Question

In PHP OOP, it is possible to call an object's parent method, by externally referencing that object?

Class ObjectOne {
    protected function method() {
        // Does something simple
    }
}

Class ObjectTwo extends ObjectOne {
    protected function method() {
        $temp = clone $this;
        $this->change_stuff();
        if(parent::method()) {
            // Do more stuff here
            $temp->method();
            // This will call this method, not the parent's method.
        }
    }

    protected function change_stuff() {
        // Change this object's stuff
    }
}

I can't call parent::method() because this will cause the current object to execute it's method. I want the $temp ones's instead.

SOLVED

I solved it by writing another function that calls the parent::update() method from inside the class:

Class ObjectOne {
    protected function method() {
        // Does something simple
    }
}

Class ObjectTwo extends ObjectOne {
    protected function method() {
        $temp = clone $this;
        $this->change_stuff();
        if(parent::method()) {
            // Do more stuff here
            $temp->update_parent();
            // This will call this method, not the parent's method.
        }
    }

    protected function change_stuff() {
        // Change this object's stuff
    }

    protected function update_parent() {
        return parent::update();
    }
}

Answer 1

$temp->parent::update()没有意义。

为什么不再做parent::update()一次而不是$temp->parent::update();

您有两个名为的方法，update()如果您调用$this->update()它，它将从调用对象的对象中调用该方法。你可以做

parent::update();

这将在类中运行update()方法ObjectOne

Answer 2

您可以使用以下语法调用任何受保护的和公共的父方法

parent::method_name();

在您的情况下，这将是： parent::update();
