note 107232 added to language.oop5.visibility

PHP does not follow Java's "Hiding Variables"[1] technique of overriding public / protected class variables but extends these variables into subclasses as normal. As mentioned by Mike Lively[2]: " ... when you redeclare protected and public variables in PHP new spaces in memory are not created, it essentially uses the same space previously occupied by your parent class’ variables. This is not true however for private variables. They will get their own distinct spaces."
