PHP Class Question

[Anon]

Can an object have an instance of another class inside it as a data member? For instance, can my "Files" class have an instance of a "User" class inside it? If so, how would I address it?

$myFileObject = new File;
$myFileObject->initializeFile($fileID);

Then in the intializeFile method, I have something like:

$this->userObject = new User;

Is this legal? If so, I guess I would access it by:

$myFileObject->userObject->initializeUser($userID);

Right? Before I write this entire thing, I'd just like to get a yay or nay :-)

Thanks in advance,
Brian

From my experience the answer to your question is no.

I wrote a class one time, and inside it I tried to instantiate another class, and PHP flagged me... after I removed code to instatiate that class - everything went smoothly.
