Hi, Lil Enid. If it has roots it may be able to survive by starting a new growth of leaves either from the base or from the spikes.
Check out the url for a discussion (with pictures) of a phal growing a new shoot from the base at Al's Orchids. Al's article also describes how to care for a phal with severely damaged top.
So it's possible. May not be worth it, tho, except as a learning exercise. Sometimes throwing it out and starting over with a healthy new plant makes more sense. It's your call.
