How do I group a div in some class on MySQL while - php

Question

I want add a different class on my MySQL result.
<?php while ($fetch = $db->fetch($query)) { ?>
<div class="result"><?php echo $fetch['title']; ?></div>
<?php } ?>
Output should be like this
<div class="group">
<div class="result">Title</div>
<div class="result">Title</div>
<div class="result">Title</div>
<div class="result">Title</div>
<div class="result">Title</div>
<div class="result">Title</div>
</div>
<div class="group">
<div class="result">Title</div>
<div class="result">Title</div>
<div class="result">Title</div>
<div class="result">Title</div>
<div class="result">Title</div>
<div class="result">Title</div>
</div>
<div class="group">
<div class="result">Title</div>
<div class="result">Title</div>
<div class="result">Title</div>
</div>
Here, every 6 results will have <div class="group"></div>.
Let me know

Answer 1

<div class="group">
<?php
$count = 0;
while ($fetch = $db->fetch($query)) {
if (++$count == 6) {
echo '</div><div class="group">';
$count = 0;
}
echo '<div class="result">' . $fetch['title'] . '</div>';
}
?>
</div>

Answer 2

create a counter that increments every time the loop is ran, then at the beginning of each loop check the value. if the value == 6 then close the current div and open a new one with the class change (you could make 2 counters to flip flop back and forth). Reset your counter after the div change.
--edit added code--
Make yourself 2 'group' div classes, 'group1' and 'group0' for the flip-flop
<div class="group1">
<?php
$count = 0;
$divstyle = 1;
while ($fetch = $db->fetch($query)) {
if (++$count == 6) {
echo '</div><div class="group'.(++$divstyle % 2).'">';
$count = 0;
}
echo '<div class="result">' . $fetch['title'] . '</div>';
}
?>
</div>

Answer 3

This might be a bit bad...
<?php $cnt=0;while ($fetch = $db->fetch($query)) { ?>
<div class="result"><?php if($cnt%6==0){echo "<div class=\"group\">";} echo $fetch['title'];if($cnt%6==0){echo "</div>";} $cnt++;?></div>
<?php } ?>
