What Wikipedia says

In organic chemistry, the phenyl group, or phenyl ring, is a cyclic group of atoms with the formula C6H5−, and is often represented by the pseudoelement symbol Ph (archaically φ) or Ø. The phenyl group is closely related to benzene and can be viewed as a benzene ring, minus a hydrogen atom, which may be replaced by some other element or compound to serve as a functional group.
