Something more along these lines:

    foreach ($numbers as $number) {

      if ($number < 1) {
        $count_less_than_one += 1;

      } else if ($number <= 1000) {
        $count_between_one_and_thousand += 1;

      } else {
        $count_greater_than_thousand += 1;
      }

    }

$count_less_than_one, $count_between_one_and_thousand, and $count_greater_than_thousand are accumulators, and shouldn't be in the condition of if(), else if() or else().

Wow thanks man. But does "+=" act the same as "++"

Not quite.

sum++ is short for sum = sum + 1

sum += n is short for sum = sum + n

So sum = sum + 1 can be shortened to either sum++ or sum += 1, but sum = sum + 2 can only be shortened to sum += 2
