While everyone's kicking in ideas...
I don't think modulus (as someone else suggested) is that expensive, but I
think this is the cheapest:
$evenodd = 0;
$color[0] = '#cccccc';
$color[1] = '#999999';
while ($row = mysql_fetch_row($st))
{
print "<tr><td bgcolor={$color[$evenodd]}>{$row['whatever']}</td></tr>";
$evenodd = 1 - $evenodd;
}
