多列动态PHP列表

Question

So what I'm trying to do is select all the distinct months from my database and then print them in a list. That, I can accomplish. The problem lies in the fact that I need my list to be two column. The way that I achieve this with CSS is by using 2 different div's "left" and "right" which are floated next to each other. This poses a problem with PHP because it needs to echo a div close and a new div open after it echoes the sixth month. Then it needs to start again from where it left off and finish. I can't just list all of the months in the HTML, either because I don't want it to list a month if I don't have any records in the DB for that month, yet. Any ideas? I hope I was clear enough!

Thanks!

Something like this should work (the basic idea being to just keep a count of the months an increment it as you loop through them):

<div class="left">

<?php
$x = 1;
foreach($months as $month) {

   # switch to the right div on the 7th month
   if ($x == 7) {
      echo '</div><div class="right">';
   }

   echo "<div class=\"row\">{$month}</div>";

   # increment x for each row
   $x++;

}

</div>
