Object Assignment

[Jarl]

Hello there.
I'm new to this board and to PHP though not to programming (mostly C++).
I should tell you before I contenue that I'm danish which means that my gramar isn't the best.
Now so far I have been learning PHP from the online manual foound on www.php.net and so far it has been smoth.
But now I've run into this which I find strange:

http://www.php.net/manual/en/language.oop5.basic.php

Look at the "Example 18-3 Object Assignment"

Now I'm a bit confuesed.
My experience with objects is from C++ and this is nothing alike.

Why is it that $instance->var = '$assigned will have this value'; effects $assigned when the only thing they have in relation is the following: $assigned = $instance;
In short the content of $instance got copied to $assigned.
There is o reference or anything

So.... how come?

I've been looking a bit at it, and now I think that understand.

$assigned becomes a reference to the INSTANCE instead of the variable.

Now it's a matter of understanding WHY it's like this in PHP while not in any other language I've seen to date.

Any help on clearing this matter?
