Protected $label = 'Unknown Item' // Rule 1 - protected. * via the getPrice and setPrice functions. ONLY floats are allowed IN & OUT of this class for $price * via the getLabel and setLabel functions. ONLY strings are allowed IN & OUT of this class for $label For example, our class definition should keep $label a string and $price a float - which means only strings can come IN and OUT of the class for label, and only floats can come IN and OUT of the class for price.

INSIDE CODE should keep the integrity of the object. When that happens, we no longer have what we expect an Item to be. As far as PHP is concerned, we can pack the entire set of Britannica Encyclopedias into the price slot.

To PHP, our Item is something with two properties (mutable in every way) and that's it. Note: we did it correctly above, but what if someone made an array for $price? FYI: PHP has no clue what we mean by an Item, especially by the terms of our class definition above. * OUTSIDE CODE can cast Item properties to any other PHP types (booleans, integers, floats, strings, arrays, and objects etc.) - another huge mistake.
