class MyClass
{
    public $var1 = 'value 1';
    public $var2 = 'value 2';
    public $var3 = 'value 3';

    protected $protected = 'protected var';
    private   $private   = 'private var';

    function iterateVisible() {
       echo "MyClass::iterateVisible:\n";
       foreach($this as $key => $value) {
           print "$key => $value\n";
       }
    }
}

$class = new MyClass();

foreach($class as $key => $value) {
    print "$key => $value\n";
}
echo "\n";
$class->iterateVisible();

在对象外只能取到权限为public的：

var1 => value 1

var2 => value 2

var3 => value 3

在对象内所有权限的都可以取到：

MyClass::iterateVisible:

var1 => value 1

var2 => value 2

var3 => value 3

protected => protected var

private => private var
