Since I don’t know if you need to return the keys or values from the array which are greater than ‘range’=>‘ANNO_IMMATRICOLAZIONE’ - or simply return false (or true) if any value is greater, I can only point you to the ‘Array Functions’ doc page.
I’m sure you can find something suitable here:

If you can be clearer what you want to return maybe I can help some more 
It would also help to know in which format your dates are stored.
I just added a post here that may help if I understand what you mean:
