Why would you ever use $ _GET in PHP?

Question

I have not officially started learning PHP, just looking through a couple of tutorials and I have a question. Why did someone decide to use Get vs Post? Why do you need the data shown in the url string? I understand that mail is used for passwords and important information, but I do not understand why you will use get, and not just publish all the time?

Thank you for understanding.
