Why are you going through all of this trouble, exactly?
If you are looking to store the instance of the object in the databaes, why not just use serialize()/unserialize()??

Couldn't you just add another method called "return_field_name()" to the class? Then you could run this method from the script and you will be given the value of the field name. Your code would look like this: class obj { var $field; function obj($value) { $this->field = $value; } function return_field_name() { return $this->field; } } then in your code you would do something like: <?php $o = new obj("field value"); print $o->return_field_name(); ?> This might not work, I don't know much about OO.
