for loop

[ojalà]

Hi!
I need help with for.
I built a web page structured in this way: I have a div that contains three columns.
I have an array that contains a list of items that I place inside of my columns.
what I can not do is build a for loop to place the elements as in the example below.

<div>
<div id="column1">
item 1
item 4
</div>
<div id="column2">
item 2
item 5
</div>
<div id="column3">
itemt 3
item 6
</div>
</div>

Thanks for help..

$output = array();
$counter = 0;
foreach($data as $value) {
  $output[$counter++ % 3][] = $value;
}
foreach($output as $column) {
  echo "<div>";
  foreach($column as $value) {
    echo "<p>$value</p>";
  }
  echo "<div>";
}
