note 72939 added to language.oop5.visibility

using visibility is a key to OOP & OOD design. To my amazement it seems most developers aren't using these key features properly. say we are creating a person and we only needed to know their height, weight & gender. BAD CLASS DESIGN <?php class A { public $height; public $weight; public $gender; public $name; public function person() { return array($height,$weight,$gender,$name) } } ?> this defeats the whole point of OO, would i implement this if i was in ASP.NET, JAVA, infact any OO lanaguage, the answer would be no. because anyone can change any property of that object, the structure is weak and isn't scalable. Try using stricter methods that restricts such tampering & allows scalability. <?php Class B { protected $property = array(); public function __get($id) { return (isset($this->property[$id])) ? $this->property[$id] : null; } public function __set($id,$val) { $this->property[$id] = $val; } } ?> although i used magic functions here the aim is keep all your class vars with as much restrictions as posible. This can now be scalabale as well say you didn't just want to get the persons attributes but wanted to extend that into what car they drive and the features of the car. then it is much easier that the first example. After seeing many post on this manual it just upsetted me that visibility is always taken for granted.
