Hi all, I've be developing with a structured approach for a long time
and am working at improving my site by adding some classes etc. I
however, am running into an odd thing that I can't figure out what a
reasonable search syntax would yield the desired solution. The problem
is as follows:

class a {

var $thisVar;
...
}

class b {

function hello()
{
echo $first->thisVar;
}
}

$first = new a();
$first->thisVar = "world";

$second = new b();
$second->hello();


There are a number of variables and methods that are common throughout
the user's session that I'm storing in object $first. Class b has
nothing in common with a except that it needs a couple of the variables
stored in the object that is hanging around in the session.

Is $first->thisVar the wrong way to reference that variable? How can I
get to it?

TIA,

Larry

Perhaps I misunderstood the problem, but I would simply...

Meine Güte wer soll das denn jetzt verstehen?
Ganz egal, komm wir bleiben noch etwas länger.

$first doesn't exist to $second - you need to make it so it knows what
it is.

class b {
var $first;
function __construct($first) {
$this->first = $first;
}

function hello() {
echo $this->first->thisVar;
}
}

then you:

$first = new a();
$second = new b($first);
$second->hello();

Thanks Chris and Robert, these both should work fine and was just what I
was looking for.
