This is a double displacement (metathesis) reaction — specifically a cation-exchange: the Na+ and K+ ions swap partners.
However, in aqueous solution all four compounds (Na3PO4, KOH, NaOH, K3PO4) are soluble, so there is no driving force (no precipitate, gas, or weak electrolyte formed). The net ionic equation is therefore
3Na+ + PO4^3- + 3K+ + 3OH- → 3Na+ + 3OH- + 3K+ + PO4^3-,
and everything cancels. So although the molecular equation shows a double replacement, the net result in solution is no net chemical change (all ions remain spectators).
