I wanted to add an alternating color in the loop. what code should I add?

Answer 1

$rowCount = 0;
$colorOne = '#ffffff';
$colorTwo = '#f3f3f3';

while($row = mysql_fetch_array($result)){
        $rowColor = ($rowCount % 2) ? $colorOne : $colorTwo; 
        echo "<element bgcolor='$rowColor'></element>";
$rowCount++;
}
