[RESOLVED] how to check if parent class is instantiated ?

[winelover]

Hi
I'm working with a class that is an extension of a parent class. As far as I can tell it instantiates its parent class like this

parent::__construct($this->sqlresultforpage[1][0]['projectid']);

how could I check if the parent is already instantiated or not ?

thanks

Does the parent class not flag itself?

I'm not sure what that means - sorry 0_o

how would it do that ?

That does not instantiate the parent class, it just (just?) calls the parent class's construct() method, to differentiate it from it's own construct() which presumably overrides the parent class's definition. This is a common practice to allow a child class to add to the constructor but then utilize the parent class's constructor before/after that customization.

ok, thanks - I think I understand that : the object is created through the child class but it has access to the methods of the parent, is that right ?

Yep. 🙂

As NogDog says, yep. Objects are instantiated (they are instances of their class); constructors are so that instantiating objects can be more elaborate than simply causing them to exist.

ok right
thanks for your help 🙂
