具有多个Mysql结果的交替CSS样式

Question

I've got a site where someone searches for x product in their location and the site spits back a list of results.

if(isset($_POST['zip'])){
$qry="SELECT business_id FROM ".TBL_BUSINESS." WHERE zip LIKE '%".$_POST['zip']."%'";
$rs = mysql_query($qry);

$rec = array();

while(($row = mysql_fetch_array($rs)) !== FALSE ){
    $rec[] = $row[0];
}

if(!empty($rec[0])){

    echo "Products for this location<br/>";

    foreach ($rec as $result)
    {
        $bid = $result;
        $qry2 = "SELECT * FROM products WHERE business_id = '".$bid."'";
        $rs2 = mysql_query($qry2);
        $rec2 = mysql_fetch_array($rs2);
        ?>
            <div class="norm">
                <img src="admin/product/img/<?php echo $rec2['image']; ?>" height="40" width="40" />
                <h3><a href="product.php?id=<?php echo $rec2['id']; ?>"><?echo $rec2['name'];?>&nbsp;&nbsp;<?php echo $rec2['prodvalue']?></a></h3>
                <div class="prodlistMeta">
                    <a class='view' href="product.php?id=<?php echo $rec2['id']; ?>">View Product</a>
                    <a class="print" href="#">Print</a>
                </div>
            </div>
        <?php
    }
}
else
{
    echo "No Product is added for this location";
}

} ?>

What would be the best way to alternate <div class="norm"> with <div class="alt">?

Answer 1

keep a counter and use it's value modulo 2 to determine whether the class should be "norm" or "alt".

 $rec2 = mysql_fetch_array($rs2);
 $count++;
   ?>
      <div class="<?php echo($count%2?"norm":"alt"); ?>">
