The private property, $door_count, can only be accessed
within the class. Echoing it outside of the class would
not work.
However, by using the get_values()
method (which is located within the class), you can call on
the private property.

/*
If you were to JUST call upon the get_values() method, the
browser would return the value, 4, as it is defined.
On the other hand, if you were to call upon the set_values()
method before the get_values() method, the browser would
return the value, 10. This is because set_values() redefines
$door_count to 10.
Since set_values() comes sequentially
AFTER $door_count is defined, the method changes its value to
10. When get_values() is called, it returns the redefined value
of $door_count.
