Removing trailing comma in loop?

[RetroDreams]

I've got a ranking script using the query below.

PHP Code:

$othervotes = $db->query_read("SELECT team, rankem_team.teamid, sum(points) AS totalpoints
FROM rankem_rank
INNER JOIN rankem_team ON rankem_team.teamid = rankem_rank.teamid
WHERE rankem_rank.weekid = $week
GROUP BY rankem_team.teamid
ORDER BY totalpoints DESC 
LIMIT 25,100");
if ($db->num_rows($othervotes) > 0)
{
while ($others = $db->fetch_array($othervotes))
{
eval('$otherbits .= "' . fetch_template('rank_otherbits') . '";');
}
} 


Here is what is in the rank_otherbits template

PHP Code:

$others[team] $others[totalpoints], 


As you can guess, there is a trailing comma. Is there a template conditional I can use to strip the last comma? If not, how can I do so programatically?
