how to sort images after readdir numerically

[anfetienne]

Hi,

What would be the best way or how should i say do i sort images that are named numerically in order?

this is my original code, i was told that it should sort perfecty fine with what ive got but it doesn't.....its all mixed up

<?php
 
$path = "upload/$random_digit/images/"; // path to the directory to read ( ./ reads the dir this file is in)
if ($handle = opendir($path)) {
   while (false !== ($file = readdir($handle))) {
    if ($file != "." && $file != "..") {
        if(!is_dir($file)){
            $item[] = $file;
            }
       }
   }
   closedir($handle);
}
 
$total_items = count($item);
$max_items = ceil($total_items / 5); // items per <td>
$start = 0;
$end = $max_items
 
//generate the table
?>
 
 
<center>
<table width="675px" border="0" cellspacing="5" cellpadding="5" align="center">
<tr>
<?php
$r = 0;
$pn=1;
$pto=1;
 
for($n=0; $n<$total_items; $n++) {
if($n !=0 && fmod($n, 5) == 0) {
echo "</tr><tr>";
}
      $imageL= $path.$item[$n];
     if (substr($imageL,-5) != 'b.jpg')
     {
      $img_path="http://theauctionwinners.com/resources/$imageL";
      $editLink = "http://theauctionwinners.com/resources/imgEdit.php?img=$img_path";
      $iframeName= 'if1';
      $iframeHeight= '955px';
      $click= 'onClick';
            // display the item
            echo '<td><center><p><a href="'.$img_path .'"><img src= "'.$path.$item[$n] .'" height="100" width="100"></a></p></center>';
            echo '<center><p><input type="hidden" name="picT[]" value="pic'.$pn++.'"/></p></center>';
            echo '<center><p><input type="hidden" name="photoT[]" value="PHOTO '.$pto++.'"/></p></center>';
            echo '<center><p><input type="text" name="captionT[]" value=""/></p></center>';
            echo '<center><p><a href="'.$editLink .'" '.$click.'="document.getElementById('.$iframeName .').height='.$iframeHeight .'; document.getElementById('.$iframeName .').src=this.href; return false;"> > Edit Image < </a></p></center><br></td>';  
    }
}
 
if($r>0) {
for($m=$r; $m<5; $m++) {
echo "<td>&nbsp;</td>";
}
}
 
?>
</tr>
<td><tr><center><input name="create" type="submit" value="Submit" /></center></tr></td>
</form>
</table>

The asort function should help with that.

For example:

<?php
$list = array(3, 6, 2, 5, 4, 1);
asort($list);
 
print_r($list);
?>

Outputs:

Array
(
    [5] => 1
    [2] => 2
    [0] => 3
    [4] => 4
    [3] => 5
    [1] => 6
)

sort($item,SORT_NUMERIC);
