By virtue of the Pegg-Barnett phase operator formalism and the numerical computation method, the phase probability distributions and the squeezed properties of number operator and phase operator for the photon-added even and odd coherent states are investigated. The results show that the phase probability distributions, which exhibit different quantum phase information and interference features, of the photon-added even and odd coherent states are different from those of the usual even and odd coherent states and even and odd nonlinear coherent states. We also find that the photon-added even and odd coherent states exhibit squeezed effects in the directions of the number operator and phase operator at different ranges of the parameter α.
