Summary 0005765: 4.0.39 subclass can not assign value to the parent protected field
Description Here is a sample
class A {
     private $_my;
     
     public function __construct(){
         
     }
     
     public function printMy(){
         print_r($this);
     }
 }

class B extends A{
     public function __construct() {
         parent::__construct();
         $this->_my = 'bac';
     }
 }

 $b = new B();
 $b->printMy();

and the output with Qurcus is
B Object ( [_my:protected] => [_my] => bac )

while in Apache is
B Object ( [_my:protected] => bac )

this caused functions in parent cannot use $this->_my to get the value where subcalss set..

 got a typo the "private" in class A should be "protected"

This is breaking Doctrine in more places than I can count, and probably any other big library making extensive use of protected visibility.

I would have reported it with major severity.

Here is another example:

    abstract class AbstractClass {
        protected $_string;

        public function getString() {
            return $this->_string;
        }
    }

    class MyClass extends AbstractClass {
        public function __construct($s) {
            $this->_string = $s;
        }
    }

    $foo = new MyClass('Foo');

    var_dump($foo->_string);
    var_dump($foo->getString());

Output:

    string(3) "Foo"
    NULL
