As the title says what I'm trying to do is count the number of images in a directory and output it as numbers so for example if there are 4 images I want the result to be:

01 | 02 | 03 | 04

I have this so far:

$count = glob('images/{*.jpg}', GLOB_BRACE);

foreach($count as $filecount) {

 echo '<li><a href="#" id="' . $filecount . '">' . $filecount . '</a></li>';

}

which outputs path/filename.jpg but haven't a clue on how to convert that to a numbers array or even if i'm in the right ballpark.

As usual all help is appreciated and thanks in advance.

Use the index. foreach ($count AS $index => $filecount) – Josh Aug 16 '11 at 3:10
Thanks that seems to work great, though had to write an "if" statement to remove the 0 count :) – Dizzi Aug 16 '11 at 3:21

That array is numerically indexed (0 to length-1 ), use it to obtain the number:

foreach($count as $index => $filecount) {
    $number = $index+1;

 foreach($count as $index => $filecount) {
      // $number is "01" for the first and "02" for second etc
      $number = str_pad($index, 2, "0", STR_PAD_LEFT);
      //...
 }
