从父类获取属性调用

Question

I have the following code:

class Page extends APage{

    /**
     * @findby selector
     */
    protected $property

    public function getPropertyCount(){
        count($this->property);
    }

}


class APage{

    protected function initPropertyByAnnotation(){

    }      

}

Im using selenium with php, In selenium you select an element with a selector. I want the parent class to detect a call to the childs property so i can handle the actual selecting.

I thought that this was possible through the __get magic method, but it turns out its only triggered when a property is not defined.

Is there a way to detect the call some way without using a helper method like getProperty?

Answer 1

You can use the __get() function changing the scope of your property to private .
As the docs says:

__get() is utilized for reading data from inaccessible properties.

public function __get($field) {
    if ($field == 'property') { //the name of your property
        //do something that you want
    }
}
