Taking into account electron-phonon interactions, the binding energy of excitons in a polar-polar semiconductor quantum well is calculated. Considering the anisotropy of cavity band, variational method was used to calculate the two-body longitudinal optical phonon modes and the four-branch interface optical phonon modes which are coupled with electrons and holes in the quantum well. contribution. Some numerical results of the system are given and discussed. The results show that bulk phonons and interface phonons play an important role in the binding of excitons. The phonon effect of binding energy is sensitive to the mass ratio of electrons to holes. The scope of the calculation is discussed
