A different (...veeeery different) approach to the good old PHP FizzBuzz test

TheUnexpectedFizzBuzz.php

<?php

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

$input = (int) $argv[1];

$fizzBuzz = [
    0 => "FizzBuzz",
    3 => "Fizz",
    5 => "Buzz",
    6 => "Fizz",
    9 => "Fizz",
    10 => "Buzz",
    12 => "Fizz",
];

for ($i = 1; $i <= $input; $i++) {
    echo ($fizzBuzz[$i%15] ?? $i) . PHP_EOL;
}
