Which One Uses Less Memory in PHP? Objects or Arrays?

Many times this question pops in my mind and many others. Obviously if it’s more to do with representing objects such as a car or a person, then we use objects as it’s a more “proper” way of doing it. However if we just want to keep a set of data in a container represented by key – value representative, which one are we going to use?

So either:

OR

The answer is objects, in general uses less memory than array.
