Description:
------------
__get() does not seem to work properly when predeclaring the property

When declared as public, __get isn't referenced, private properties are being redeclared as public!

Reproduce code:
---------------
class param
{
    public $a;
    private $b;
    function __get($memberName)
    {
        switch($memberName)
        {
            case 'a':
                $var = 'a';
            break;
            case 'b':
                $var = 'b';
            break;
        }
        return $var;
    }
}

$p = new param();
$a = $p->a;
$b = $p->b;

Expected result:
----------------
$a = 'a'
$b should throw an error, since param->b has been declared as private

Actual result:
--------------
$a = ''
$b = 'b'
