Matchsticks, as you have surely noticed, consist of a head and a wooden stick. The head usually contains potassium chlorate, an oxidizing agent, a small quantity of powdered glass that provides the essential friction while striking, animal glue to bind some other abrasives, and additive compounds like sulphur or antimony (III) sulfide that act as fuel. The wooden stick also has a certain substance, typically ammonium phosphate, impregnated in its composition to suppress the afterglow once the flame dies. The other part is the striking surface, which usually consists of red phosphorus, powdered glass (or silica), binder and filler.
When you rub the stick against the striking surface, the friction generated causes some of the red phosphorus present to turn into white phosphorus. Now, white phosphorus is highly sensitive and volatile; it ignites spontaneously in the air, making a flame. Once the stick has a flame at one end, all it needs to do is sustain it by providing it with more oxygen (oxidizing agent) than it can get from the air directly, and by giving it something to burn.

... down potassium chlorate, releasing a lot of oxygen for the flame to become larger. This oxygen combines with the sulphur contained in the head to sustain the miniature fire. Once the flame lives through its eventful initial phase, all it has to do is burn up the length of the wooden stick in the presence of atmospheric oxygen.
