Project Euler Question

The sum of the squares of the first ten natural numbers is,
$$1^2 + 2^2 + ... + 10^2 = 385$$
The square of the sum of the first ten natural numbers is,
$$(1 + 2 + ... + 10)^2 = 55^2 = 3025$$
Hence the difference between the sum of the squares of the first ten natural numbers and the square of the sum is $3025 - 385 = 2640$.
Find the difference between the sum of the squares of the first one hundred natural numbers and the square of the sum.

Solution Code:

      <?php

  function code_solution_6() {
    $numbers = range(1,100);
    $value1 = pow(array_sum($numbers),2);
    $value2 = 0;
    foreach($numbers as $number) {
      $value2 += pow($number,2);
    }

    return $value1 - $value2;
