I typically like there to be enough copies of the PHB aroudn so that each spellcasting character can look things up quickly. But I don't require that peole buy them.
With books that contain feats, races, and classes you really don't need one per player. They only get used occasionally (when levelling, or creating a new character). At that point, sharing them around is reasonable.
