What is the difference Between Cache and Session | Cache Vs Session in PHP

In a recent project I had to use Session and Cache Both. But I wasn't aware of what's the major difference in Session as well as Cache. Because in that time I used to think as if both are storing some data which we can use further use. Actually the concept is same. But There is some Major differences as well. So Let's see what's that:

Cache can expire after a specific time means we can put some specific amount of time with cache whereas one an Item put into session can stay there forever until the session ends.
