why uninitialized property is made public in class?

Question

Consider below code please:

class foo {
    function bar() {
        $this->baz = \'hello there!\';
    }
}

$f = new foo;
$f->bar();
echo $f->baz; // h         


        

Answer 1

Who told that you are not initialized,You have initialized by the statement $this->baz = 'hello there!'; This is how object oriented concept works.You are declaring a class , creating an instance for that class and then accessing that function and at last echoing a variable in that member function,This is how object orientation works...
