Raindrops

Welcome to Raindrops on Exercism's PHP Track. If you need help running the tests or submitting your code, check out HELP.md.

Introduction

Raindrops is a slightly more complex version of the FizzBuzz challenge, a classic interview question.

Instructions

Your task is to convert a number into its corresponding raindrop sounds.

If a given number:

• is divisible by 3, add "Pling" to the result.
• is divisible by 5, add "Plang" to the result.
• is divisible by 7, add "Plong" to the result.
• is not divisible by 3, 5, or 7, the result should be the number as a string.

Examples

• 28 is divisible by 7, but not 3 or 5, so the result would be "Plong".
• 30 is divisible by 3 and 5, but not 7, so the result would be "PlingPlang".

• 34 is not divisible by 3, 5, or 7, so the result would be "34".

  A common way to test if one number is evenly divisible by another is to compare the [remainder][remainder] or [modulus][modulo] to zero.
  Most languages provide operators or functions for one (or both) of these.

A variation on FizzBuzz, a famous technical interview question that is intended to weed out potential candidates. That question is itself derived from Fizz Buzz, a popular children's game for teaching division. - https://en.wikipedia.org/wiki/Fizz_buzz
