Order results

Been capable of sorting results (ASC, DESC) by total wordcount or nº of comment would be great. I hardcoded a sorting method for total (DESC) in wordcount_show_count() function this way:

foreach ($row as $k=>$v) {
$row[$k]['avg_post'] = ($row[$k]['posts']) ? number_format($row[$k]['num_words_post']/$row[$k]['posts'], 1) : 0;
$row[$k]['avg_comment'] = ($row[$k]['comments']) ? number_format($row[$k]['num_words_comment']/$row[$k]['comments'],1) : 0;
$row[$k]['total'] = $row[$k]['num_words_post'] + $row[$k]['num_words_comment'];
}

// NEW CODE

function cmp($a, $b) {
if ($a["total"] == $b["total"]) {
return 0;
} else {
return ($a["total"] > $b["total"]) ? -1 : 1;
}
}

usort($row, "cmp");

// END OF NEW CODE

$header = array(
array ('data' => 'id'),
...

Not going to win a PHP coding contest, but works for me
