<?php
// 7 kyu - Fibonacci's FizzBuzz
// The goal of this kata is two-fold:
//
// 1.) You must produce a fibonacci sequence in the form of an array, containing a number of items equal to the input provided.
//
// 2.) You must replace all numbers in the sequence divisible by 3 with Fizz, those divisible by 5 with Buzz, and those divisible by both 3 and 5 with FizzBuzz.
//
// For the sake of this kata, you can assume all input will be a positive integer.
//
// Use Cases
// Return output must be in the form of an array, with the numbers as integers and the replaced numbers (fizzbuzz) as strings.
//
// Examples
// Input:
//
// fibs_fizz_buzz(5);
// Output:
//
// [ 1, 1, 2, 'Fizz', 'Buzz' ]
// Input:
//
// fibs_fizz_buzz(1);
// Output:
//
// [1]
// Input:
//
// fibs_fizz_buzz(20);
// Output:
//
// [1,1,2,"Fizz","Buzz",8,13,"Fizz",34,"Buzz",89,"Fizz",233,377,"Buzz","Fizz",1597,2584,4181,"FizzBuzz"]
