Counting in ruby and php.

counting.php

<?php

function countBy($x = 1, $to = 100)
{
    return range(0, $to, $x);
}

function countOccuranceOf($value, $array)
{
    $counts = array_count_values($array);
    return (array_key_exists($value, $counts)) ? $counts[$value] : 0;
}

counting.rb

def count_by(x = 1, to = 100)
  (0..to).step(x)
end

def count_occurance_of(value, array)
  array.count(value)
end

Okay, so I guess PHP has some functions to do this. I was originally thinking I'd need loops. But the PHP manual shows some functions I must have missed the first time I read through it (from cover to cover). Still, I find the ruby syntax to be superior, and -- still -- more compact.
