When iterating over an array you can get both the value of the current item as well as its key by using foreach ($array as $key => $value).

foreach ($objects as $index => $object) {
    print_r($index.' '.$object->value1)
}

Objects are not arrays. Does foreach work on objects?

First and foremost, yes foreach works on objects by iterating over their public properties (or if they implement special interfaces the iteration does whatever the method implementations do).
