Question

I’m using DirectoryIterator to list files. In this scenario my dir contains 19 files.

I need to create a list which wraps 7 files into a <div>.

I must be tired, because I’m not able to do this simple task.

My code is updated to reflect suggestions below:

$i = 0;
echo '<div class="first_div">';

foreach ($dir as $fileinfo) {
  if ($fileinfo->isFile()) {
    if(($i % 7 == 0) && ($i > 0) )
      echo '</div><div>';

    echo 'My file';
    $i++;
  }
}
echo '</div>';

Any help appreaciated.

Try using the mod operator (%) to determine if the current file number is the 7th one:

echo "<div>";
$i = 0;
foreach ($dir as $fileinfo) {
   // Remainder is 0, so its the first of 7 files. 
   // Skip this for the first one, or we'll get a blank div to start with
   if($i % 7 == 0 && $i>0) echo "</div><div>";
   echo $filenamehere;
   $i++;
}
echo "</div>";

(Code is untested but should work)

EDIT : Used an independent counter for $i, since the index seemed to start at 2 and not 0 as expected.
