TheUnexpectedFizzBuzz.php

#!/usr/bin/env php
<?php

if ($argc !== 2 || !ctype_digit($argv[1]))
  die('You must specifiy only one parameter: the max number as an integer' . PHP_EOL);

for ($input = (int) $argv[1], $i = 0; $i < $input; ) echo ([
  0 => 'FizzBuzz',
  3 => 'Fizz', 6 => 'Fizz', 9 => 'Fizz', 12 => 'Fizz',
  5 => 'Buzz', 10 => 'Buzz',
][++$i % 15] ?? $i) . PHP_EOL;
