$object->$var makes no sense.  Unless $var is set to 'var' in which case
it is the same thing and you will get the same fatal error as on the
line before.  The only way for $object->$var to print 2 in your example
is if you have $var = 'foo' and MyClass has a public property named foo
with a value of 2.
