Using code tags properly

 

Since Unity doesn't run PHP, this means you're contacting another server.

To do so you will need UnityWebRequest().

Anytime you are doing networking, ALWAYS START HERE:

Networking, UnityWebRequest, WWW, Postman, curl, WebAPI, etc:

And setting up a proxy can be very helpful too, in order to compare traffic:

If this is your first game, don't even THINK about doing networking. Finish about a dozen or so regular simple games (think Angry Birds or Flappy Birds) until you are completely at home with Unity before you attempt something as complicated as networking.
