Some OOP Questions

[Anon]

I was wondering.
I am trying to do a game manager and will have some classes.
Tournament, Team, Player an a mySQL class.

What is the easiest way to do so you can use the mySQL class in all of the other classes, and class Team should allso use the Player class, the Tournament class should allso use the Team class and the Player class.

Should I create an instance of the classes I want to use and send them to the constructor of each class or how should I do?

Hope you understand what I am trying to do here.

Thanks in advance!

I'm not sure i fully understood what u asked,but...

If u want to use the same instances of classes throughout the whole program,why don't u declare those instances as global?

If u need new instanses of the classes each time u use it ( i wonder,why would u😉)) ,
include a variable of needed class into the parent class.

Sorry if it's totally off the subject.

All the best.

Just Extend!!! 🙂

class mySQL {

}

class Player extends mySQL {

}

class Team extends Player {

}

class Tournament extends Team {

}

so your hieracarchy looks like

mySQL --
\
Player--
\
Team--
\
Tournament

Hope this helps....

(Fair warning its really late and I am really tired so if this isnt what you wanted, blame it on lack of sleep 🙂 )

Ok, I think this is what I wanted.
If this means that class Player extends the mysql class, and then the classes that are extending the Player class, can use the mysql-class as well?

Thanks !

Yes! Just remember to use the default constructors, created by PHP.

Ahhhh Inheritance!! 🙂
