The amplitude for $\gamma p \to \phi p$ is calculated in a pQCD $k_{T}$ -factorization approach. The total cross section for this process is comparedwith HERA data. Total cross section, as a function of photon-proton energy andphoton virtuality, is calculated. We also discuss the ratio of $\sigma_{L}$ /$\sigma_{T}$ and the dependence on the mass of the strange quark. The amplitudefor $\gamma p \to \phi p$ is used to predict the cross section for exclusivephotoproduction of $\phi$ meson in proton-proton collisions. Absorption effectsare included. The results for RHIC, Tevatron and LHC energies are presented.
