$a->b indicates that b is a member of object a. It's the PHP equivalent
of "." in Java.
In PHP, all object members must be referred to with their parent object,
even inside their own functions. That would be $this->function() or
$this->variable.
(Note that "->" is only used for objects. Static members of a class are
referred to with ClassName::member)
