Actually, there are two reaction involving:

P4+3NaOH+3H2O⟶PH3+3NaH2PO2PX4+3NaOH+3HX2O⟶PHX3+3NaHX2POX2

White phosphorus react with sodium hydroxide and water to produce phosphine and sodium hypophosphite . Sodium hydroxide - cold, concentrated solution. This reaction takes place slowly. (Chemiday 1)

The O.S. of phosphorus in sodium hypophosphite is calculated in @Sayantan.G's answer.

P4+8NaOH+4H2O−→Δ4Na2HPO3+6H2PX4+8NaOH+4HX2O→Δ4NaX2HPOX3+6HX2

White phosphorus react with sodium hydroxide and water to produce disodium hydrogen phosphite and hydrogen. Sodium hydroxide - concentrated solution. The reaction takes place in a boiling solution.(Chemiday 2)

The O.S. of phosphorus in disodium hydrogen phosphite is:

+2⋅1+1+x+3⋅(−2)=0+2⋅1+1+x+3⋅(−2)=0

x=+3

Answer:

White phosphorus reacts with caustic soda to give phosphine and sodium hypo phosphate. White phosphorus reacts mainly with oxygen in the water and may stay in water for a period of hours to days.
