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?

$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();
