Overriding private property in PHP

Question

Can't explain why this prints "\n1". Private property can't be inherited. That's why constructor should set value of new defined public proverty, but "print $b->number" prints nothing whereas "$b->printNumber()" prints "1".

class A { private $number; public function __construct($number) { $this->number = $number; } public function printNumber() { print $this->number; } } class B extends A { public $number; } $b = new B(1); print $b->number; print "\n"; $b->printNumber();

The private is defined in "A". As printNumber() is also defined in "A" it will access $this->number in the scope of class "A". So the result is expected.

class B extends A { public $number; public function __construct($number) { $this->number = $number; } }

Of course you would never override a private with a public ;)
