In this case, I would have choose objects since the data may keep changing and i also want the data to be secure. So. i'll go with objects. But when you say the parameters in objects then obviously hash or array will be used for that. I'm using object just to make the code to work faster and use only required data not to run unnecessarily the whole code. Now, it's on you which approach suits you better. Go ahead with a practical demonstration too and use timer function to check the time consuming.
