The Ethernet PIC18s contains, as you say, both MAC and PHY. They only
need the magnetics and an RJ45 connector (which can be combined).

Some PIC32 (not all) has a built in Ethernet controller and it
contains the MAC but not the PHY. They use the MII or RMII hardware
and register interface. A LAN8720 is a good pick for the PIC32 with
built in MAC. It is small, cheap and supported by the Microchip
stack.

For all other PICs (PIC32 or not) that don't have the Ethernet
controller you need something like the ENJ circuits and enough memory
in the PIC.
