How to present a list in chunks using php?

I wish to display a (flat) list of records in chunks of 3 items like this:

<div class="wrapper">
  <div id="item1"></div>
  <div id="item2></div>
  <div id="item3"><div>
</div>

<div class="wrapper">
  <div id="item4"></div>
  <div id="item5></div>
  <div id="item6"><div>
</div>

Those item1 to n will be retrieved from a db query.

The problem are the wrapper divs. It seems I need to slit a foreach in n chucks?

Can I have a little push here?

<?php
function renderWrapperStart($i) {
    if ($i % 3 !== 0) {
        return;
    }
?>
    <div class="wrapper">
<?
}

function renderWrapperEnd($i) {
    if ($i % 3 !== 0 || $i == 0) {
        return;
    }
?>
    </div>
<?
}

function renderItem($i, $id, $content) {
?>
    <div id="<?= $id ?>"><?= $content ?></div>
<?
}

$items = array(
    'item1' => 'content 1',
    'item2' => 'content 2',
    'item3' => 'content 3',
    'item4' => 'content 4',
    'item5' => 'content 5',
    'item6' => 'content 6'
);

$i = 0;

foreach ($items as $id => $content) {
    renderWrapperEnd($i);
    renderWrapperStart($i);
    renderItem($i, $id, $content);
    $i++;
}

renderWrapperEnd($i);
?>

Output is:

<div class="wrapper">
        <div id="item1">content 1</div>
        <div id="item2">content 2</div>
        <div id="item3">content 3</div>
</div>

<div class="wrapper">
        <div id="item4">content 4</div>
        <div id="item5">content 5</div>
        <div id="item6">content 6</div>
</div>

$end = 20;

for($count = 1; $count <= $end; $count++){

    if(($count % 3) == 1)
        echo '<div class="wrapper">';

    echo '<div id="item'.$count.'"></div>';

    if(($count % 3) == 0 || $count == $end)
        echo '</div>';
}

EDIT (separated the HTML from PHP per request in comments):

$end = 20;

for($count = 1; $count <= $end; $count++){

    if(($count % 3) == 1){
        ?>
            <div class="wrapper">
        <?php
    }

    ?>

    <div id="item<?=$count?>"></div>

    <?php
    if(($count % 3) == 0 || $count == $end){
        ?>
            </div>
        <?php
    }
}

is this what you want ?

for($i=1 ; $i<= n ; $i++){
  if($i%3 == 0) {
      echo '<div class="wrapper">';
  }
  echo '<div id="item'.$i.'"></div>';
  if($i%3 == 0) {
     echo '</div>';
  }
}

array_chunk($arr, 3);
