Php Inheritance

[vrynxzent]

I am using PHP 5.3 stable release and sometimes I encounter very inconsistent behaviours. As far as I know in inheritance all attributes and methods(private, public and protected) in super class are passed child class.\[code\]class Foo{ private $_name = "foo";}class Bar extends Foo{ public function getName() { return $this->_name; }}$o = new Bar();echo $o->getName();//Notice: Undefined property: Bar::$_name in ...\test.php on line 11\[/code\]But when Foo::$_name attribute is defined "public" it doesn't give error. PHP has own OO rules???ThanksEdit: Now all things are clear.Actually I was thinking in "inheritance" a new class is created and inherits all members independent from its ancestor. I didn't know "accessing" rules and inheritance rules are the same.EditAccording to your comments this snippet should give an error. But it is working.\[code\]class Foo{ private $bar = "baz"; public function getBar() { return $this->bar; }}class Bar extends Foo{}$o = new Bar;echo $o->getBar(); //baz\[/code\]
