List node count for each node type

This snippet is will return a table with each node type and the number of nodes published for each type over the past three years

Snippet:

<?php
#in template.php:
function custom_count_pull(){
    $sql = "SELECT type, COUNT(nid) AS number, FROM_UNIXTIME(created, '%Y')  AS createdate FROM {node} GROUP BY type, createdate ORDER BY createdate DESC";
    $result = db_query($sql);
    $article_count = array();

    while ($data = db_fetch_object($result)){
        if (isset($article_count[$data->type])) {
      
            $article_count[$data->type][$data->createdate] = $data->number;
        } else {
            $article_count[$data->type] = array($data->createdate => $data->number);
        }
    }
    $today = date("Y");
    $years = array($today-2,$today-1,$today);

    $output .= "<table><tr><th>Type</th><th>{$years[0]}</th><th>{$years[1]}</th><th>{$years[2]}</th></tr>";  
    foreach ($article_count as $type => $value) {
        $real_type_name = node_get_types('name', $type);
        $output .= "<tr> <td>$real_type_name</td>";

        foreach ($years as $year) {
            if ($value[$year]):
            $output .= "<td>{$value[$year]}</td>";
            else:
            $output .= "<td>0</td>";
            endif;
        }
        $output .= "</tr>";
    }
    $output .= "</table>";
    return $output;
}

#in node.tpl, page.tpl or block.tpl
print custom_count_pull();
