What does it do then?

Phosphorus is a component of the nucleic acids RNA and DNA which are important in cell multiplication and growth. Phosphorus is part of a molecule called ATP which is involved in energy transfer inside cells.  Also, phosphorus is an important component of cell membranes where it plays a role in the interaction between the cell membrane surface and nutrients in the growing medium.
Potassium which is next to nitrogen is the mineral nutrient required in the largest amount by plants. Potassium is important in a plants ability to handle stress from environmental factors like pathogens, drought, frost etc. Potassium also plays a very important role in osmoregulation or the control of the amount of water inside cells.
