确定使用parent :: __ construct（）的子类;

Question

I have a situation where I need to pass the name of the child class back to the parent class in order to take some action.

The way I have it set up at the moment is:

class SomeParentClass {

    public function __construct($c = false){
        ...
    }

}

class SomeChildClass extends SomeParentClass {

    public function __construct(){
        parent::__construct(__CLASS__){
            ...
        }
    }

}

This will pass the name of the child class back to the parent, but if the child class does not do this then the variable $c will retain the bool value false.

It works, it makes sense, but is this the cleanest way to do this? Is there a way to auto detect which child class has called parent::__construct() without passing it as a variable?

Many thanks

You can do this with get_called_class() ( http://php.net/manual/en/function.get-called-class.php ) in PHP 5.
