PHP在行数除以4后得到<div>

Question

I need to divided all data into 4 columns. i have used this method but its not coming column property

   $stmt1 = $db->prepare($sql1);
   $stmt5 = $db->prepare($sql1);
   $stmt5->execute();

   $rowcount = $stmt5->rowCount();

   $pages = ceil($rowcount / 4);
   $tempcount = 1;

if ($stmt1->execute(array())) {
   while ($row = $stmt1->fetch()) {
   ?>

       <?php if ($tempcount == $pages) { ?>

         <div class="column">
         <div class="ui bulleted list">

      <?php } ?>

          <a href="" class="item">  </a>

     <?php
     if ($tempcount == $pages) {
      $pages = $pages + $pages; ?>

          </div>
          </div>

     <?php }
     $tempcount++;
      }
       } ?>

how i can get this columns after getting count of data i have and add those divs in between.

for an Example 20 data rows 20/4 = 5 after each 5 data, i need start and end to be added

    <div class="column">
    <div class="ui bulleted list">

      <a href="" class="item">  </a>
      <a href="" class="item">  </a>
      <a href="" class="item">  </a>
      <a href="" class="item">  </a>
      <a href="" class="item">  </a>

   </div>
   </div>
   <div class="column">
    <div class="ui bulleted list">

      <a href="" class="item">  </a>
      <a href="" class="item">  </a>
      <a href="" class="item">  </a>
      <a href="" class="item">  </a>
      <a href="" class="item">  </a>

   </div>
   </div> 

// And so on

result will be like this

thank you very much

Here's a proper code with comments

$tempcount = 0;
$pages = ceil($rowcount / 4);
while ($row = $stmt1->fetch()) {

    // if result of % (Modulo) is zero - you need to start new column
    if ($tempcount % $pages == 0) {?>
    <div class="column">
         <div class="ui bulleted list">
<?php
    }?>
     <a href="" class="item">ITEM</a>
<?php

    // if result of % (Modulo) is (pages - 1) - you need to close previous column
    if ($tempcount % $pages == ($pages - 1)) {?>
        </div>
    </div>
<?php
    }
    $tempcount++;
}

// check if you have to close previous column 
// because it was not closed in a while loop


if (0 < $rowcount) {
    if ($tempcount % $pages != 0) {?>
            </div>
        </div>
    <?php
    }
}
