Help with designing objects

[airportmarc]

Hello all,

 

So I have created an internal messaging system for our users, and while it works, I wanted to grow my OOP knowledge.  So I have 2 objects, message, and messageControl.

 

What I wanted to know was what should do what?  For example, should the message be able to send itself, or is that the job for messageControl?  Also, in the message class I have a method that displays itself, is that ok or should that be handled somewhere else (I can see this looking like MVC). 

 

On the site I have other objects where I run into the same problem of what should handle what.  On the site an admin can approve or deny a users request.  I have an object request and requestControl.  What object should handle the approve/Deny process?

 

While not new to PHP, my OOP design knowledge is lacking.

 

Thanks for your help,

 

Marc

Something to get you started

 

$postOffice = new PostOffice();
$message = new Message($_POST, $sender);
$postOffice->distr($message, $receivers);
