Hello Curt,
From http://us2.php.net/manual/en/language.operators.assignment.php
"The value of an assignment expression is the value assigned.
That is, the value of "$a = 3" is 3."
I take this to mean that ($foo->a = 'bar') will always return 'bar'
and that is a core feature of the language. Remember that $foo->a is
the left hand operand, and is only receiving the value. It is the =
operator that returns the value of the expression.
It may also be worth noting that the Associativity of the `=` operator
is "Right".
