[php] iterating through a folder 4 at a time

[ringo747]

hi guys,

my head isn''t with it today and i'm working on a script which iterates through all the images in a folder and outputs the images in a table. I want to limit each iteration to 4 images i.e. I want to output the following..

<tr>
.... <td><img 1
.... <td><img 2
.... <td><img 3
.... <td><img 4
</tr>
<tr>
.... <td><img 5
.... <td><img 6
.... <td><img 7
.... <td><img 8
</tr>

How can I possibly iterate through the first 4 files, output a row end tag </tr> and a new row tag <tr> and then iterate through the next 4 etc.

The result is needed so that I can display the images (4 to a row in a gallery).

Sorry if this seems like a stupid request but I can't work it out!

edit:
This is the top of my code

if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {

Also if I could page the output based on the total number of images that would be very handy.

Thanks for that guys... so to add that to my own code it would be something like....

if (is_dir($dir)) {
 if ($dh = opendir($dir)) {
  while (($file = readdir($dh)) !== false) {

foreach (range(0,count($file)) as $i) {
  if ($i % 4 == 0) {
    echo '</tr>......something..........<tr>';
  }
  else {
      echo '........something.......';
  }

Would this work or will it not like me embedding the foreach within a while loop?

How about... wait for it... you try it and see?

no point in crawling round the code for another few hours until im sure if i've got the concept right! cheers for your valuable input sir
