用while更改div的值

I need put this divs in this order:

<div class="col-md-9"> 1 box </div>
<div class="col-md-3"> 2 box </div>
<div class="col-md-3"> 3 box </div>
<div class="col-md-9"> 4 box </div>
<div class="col-md-9"> 5 box </div>
<div class="col-md-3"> 6 box </div>
<div class="col-md-3"> 7 box </div>
<div class="col-md-9"> 8 box </div>

An continue in this order. I try make it with a while but I can't find an algoritm that put me the divs in this order.

This is the code that I try but don't work:

$count = 0;

    while($items = mysql_fetch_array($consult))
    {
        if($count % 2 == 0)
        {
            echo '<div class"col-md-9"> '.$items['title'].' </div>';
        }
        else
        {
            echo '<div class="col-md-3"> '.$items['title'].' </div>';
        }
    }

This show me:

<div class="col-md-9"> value </div>
<div class="col-md-3"> value </div>
<div class="col-md-9"> value </div>
<div class="col-md-3"> value </div>

Any idea?

Regards

    1st: don't use MYSQL_* commands, they are deprecated and unsafe!

    2nd: This should do. Notice: I did not test it, just wrote a quick example:

    $count = 1;
    $md = 9;
    
    while ($items = mysql_fetch_array($consult)) {
        $count++;
        echo '<div class="col-md-' . $md . '"> ' . $items['title'] . ' </div>';
    
        if ($count > 1) {
            $md = $md == 3 ? 9 : 3;
            $count = 0;
        }
    }
