The production of {phi} mesons in proton-proton collisions is investigated within a relativistic meson-exchange model of hadronic interactions. The experimental prerequisites for extracting the NN{phi} coupling strength from this reaction are discussed. In the absence of a sufficient set of data, which would enable an accurate determination of the NN{phi} coupling strength, we perform a combined analysis, based on some reasonable assumptions, of the existing data for both {omega}- and {phi}-meson production. We find that the recent data from the DISTO Collaboration on the angular distribution of the {phi} meson indicate that the NN{phi} coupling constant is small. The analysis yields values for g{sub NN{phi}} that are compatible with the Okubo-Zweig-Iizuka rule. {copyright} {ital 1999} {ital The American Physical Society}
