Creating PHP Functions

Sprout Video

You've come a long way already, which has included using a bunch of existing, built-in functions. Now it's time to make our own! The first thing our PHP code does right now is read our pets.json file and decode it into an array, which we set on our $pets variable. Let's invent a new function called get_pets() that will do this work for us and return the finished array. Putting this into a function lets us reuse this logic whenever we want, in other places in our code, without having to write it all out again. This also makes organizing and updating our code more straight-forward and simple.
