$var is empty, so this is setting a non-existent class property to 2.
> $object->printVar(); // prints 2
I got 1 when running this -- just as I would expect. Are you sure it
printed 2?
Basically, if a property is undeclared, it is assumed public, so you can
set undefined properties without issue. If defined private or protected,
the calling script will not be able to alter the value.
