How to get code and access_token from FB via curl?

Question

PHP

Faced a problem, you need to get the code from https://www.facebook.com/dialog/oauth/
from the console and then make a request with this code to https://graph.facebook.com/oauth/access_token to get the token and work with api fb.
I can not understand how to implement it correctly through curl .
I looked all over the stack-overflow and didn't find anything useful. Maybe someone has an example?
