Thank you for your report.
The behavior you describe is not a bug. The statement
$obj2->private = "Hacked";
does not change the private property of MyClass. Instead, it creates a
new public property on MyClass2.

<?php
class MyClass {
private $private = 'Private';
}
class MyClass2 extends MyClass {
protected $protected = 'Protected2';
}
$obj2 = new MyClass2();
$obj2->private = "Hacked";
echo $obj2->private; // should be fatal error by accessing the private
property, but it displays the string "Hacked"
?>

protected $protected = 'Protected';
private $private = 'Private';
function printHello()
{
echo $this->public;
echo $this->protected;
echo $this->private;
}
}
$obj = new MyClass();
echo $obj->public; // Works
//echo $obj->protected; // Fatal Error
//echo $obj->private; // Fatal Error
$obj->printHello(); // Shows Public, Protected and Private
/**
* Define MyClass2
*/
class MyClass2 extends MyClass
{
// We can redeclare the public and protected method, but not
private
protected $protected = 'Protected2';
function printHello()
{
echo $this->public;
echo $this->protected;
echo $this->private;
}
}
$obj2 = new MyClass2();
echo $obj2->public; // Works
echo $obj2->private = "Hacked";
echo $obj2->private; // Undefined

?>
