What is the difference between $ _ENV, $ _SESSION and $ _COOKIE

Question

I mainly used $ _ SESSION , but reading about the session, I got a few terms

$ _ ENV &

$ _ COOKIE .

I don’t understand when to use which one, I got confused in a situation where I can use them. So how do these terms differ?
