Advanced Question - Class cannot store variable

[jaycode]

Hi, I created this class in admin/includes/classes:

    class Designer{
        var $attributes, $values;
        
        function Designer($values = "") {
        $attributes = explode(",",DB_DESIGNERS_ATTRIBUTES);
        print_r($attributes);
            if (!is_array($values)) {
                $values = str_replace(" ", "", $values);
                $values = explode(",", $values);
            }
            $this->values = $values;
            return true;
        }
        
        function getDesignerAttributes() {
            echo $attributes;
            print_r($attributes);
            return $attributes;
        }
        ...
    }

And I am trying to use that class in my own page, say admin/gallery.php:

$new_designer = new Designer($values);
$a = $new_designer->getDesignerAttributes();
echo($a);
print_r($a);

Why even though I have written this colored codes, this colored commands didn't return any value, but this colored commands return the correct values.

I hope people from the development team can help with this, and I need this help kinda fast, so pleeease if you have any reply, don't hesitate ok...

thanks guys
