What actually is d π (pi )-pπ (pi)bonding ?Does phosphorus show d π (pi )-pπ (pi)bonding ?

Pi bonding refers to sidewise overlapping of orbitals . Therefore d-pi- p-pi refers to when one d orbital and p orbital of another atom overlap sidewise to form a pi bond .
Yes phosphorus shows dΠ - pΠ in POCl3 or similar species . O=P(Cl)(Cl)Cl

POCl3  is a sp3 hybridized , so 1 s and 3 p orbitals will used for making sigma bonds . But there is still one pi bond between P and O , So d orbital of phosphorus will be used for sidewise overlapping with an p orbital of Oxygen .

i hope you have understood . :)
