I have just recently began learning PHP. I have a pretty solid foundation in general programming and PHP. As my first major PHP project I am trying to make myself an autobuyer for Fifa 15 using curt2008 Fifa API. He basically has everything there for me to use and I know that I have enough knowkledge to get a basic autobuyer going if I could just figure out how to log in. I have come to realize that the problem is that I have no idea what he is doing when he connects to the Fifa Web App. He has the code there for me, but I don't know what it is actually doing. I was hoping someone can point me to some documentation, a tutorial, or even exercises so that I may learn more about... logining into a web application? I don't even know what to call it.
Looking at connect.php he has a bunch of functions. Login, getSessionID, Phishing, getNucleusID, getShards, and all of them do a bunch a requests and use a bunch of headers. I don't know what this terminology is or how it all works together, but I would like to learn about it. Thats why I wanted to start learning PHP, for stuff like this. I just don't know where to look.
Thank You
