Hi, i have found the following snippet of code which i am modify make part of an image gallery script i am making, the trouble i'm having is the way it's sorting files.

At the minute the following code will just produce a list of all the files found in the directory.

PHP Code:

<?



//define the path as relative

$path = "/home/httpd/vhosts/spoono.com/httpdocs";



//using the opendir function

$dir_handle = @opendir($path) or die("Unable to open $path");



echo "Directory Listing of $path<br/>";



//running the while loop

while ($file = readdir($dir_handle)) 

{

   if($file!="." && $file!="..")

      echo "$file<p>";

}



//closing the directory

closedir($dir_handle);



?>

the problem is the way it handles filenames with numbers in.. i.e

if i have the following files

image1.jpg
image2.jpg
image11.jpg
image19.jpg
image21.jpg

it doesn't display in that order it does it in this order

image1.jpg
image11.jpg
image19.jpg
image2.jpg
image21.jpg

does anybody have any idea how to fix this so it lists how it should? im planning on just numbering my images like that to order them and it'd be a pain if i have to take that in to account when numbering them..

thanks for any help

The OS isn't always going to return a sorted list of files in a directory. You could use glob() (http://us2.php.net/glob) for that.

If you have control over the filenames, it also helps to name them with zero-padding, like:
image-00000001.jpg
image-00000010.jpg
image-00000100.jpg
image-00001000.jpg

As long as you don't change the way you are naming your image files, then this code will sort them in the proper order.
This code allows up to 999 files.
If you need room for more than that, then I will show you how to modify the code to accept more.

PHP Code:

<?php
//define the path as relative
$path = "/home/httpd/vhosts/spoono.com/httpdocs";
//using the opendir function
$dir_handle = @opendir($path) or die("Unable to open $path");
//running the while loop
$ct=0;
while ($file = readdir($dir_handle))
{
   if($file!="." && $file!="..")
   {
    $temp[0][$ct]=substr($file,5,3)?substr($file,5,3):"";
    $temp[1][$ct]=$file;
    if(substr($temp[0][$ct],1,1)=="."){$temp[0][$ct]="00".substr($temp[0][$ct],0,1);}
    if(substr($temp[0][$ct],2,1)=="."){$temp[0][$ct]="0".substr($temp[0][$ct],0,2);}
    $ct++;
    }
}
//closing the directory
closedir($dir_handle);
echo "Directory Listing of $path<br/>";
// Sort dir_names
array_multisort($temp[0],$temp[1]);
for($i=0;$i<count($temp[0]);$i++)
{
 echo $temp[1][$i]."<p>";
 }
?>
