This is Rails parameter naming converion
phones[#{phone.id}][phone] means that the corresponding input element
will (in the controller) be at params['phones']['25']['phone']

The 'new' is presumably just a convention by whoever wrote this code
to indicate a new record.

Not sure what you're asking about. params is just a regular hash,
they're pulling out the value with key "person"
