problems reading files from directory - doesnt display in order :(

[LJackson]

Hi All,

I have a gallery php page which gathers the photos from a specified directory or images, it is working ok but the major probem im having is that it doesnt always display the files in order.

By this i mean if my images are titled img0, img1, img2 .... img10, img11, img12

they are ordered like so
img0, img1, img10, img11, img12, img2

and not like
img0, img1, img2, img10, img11, img12

does anyone know how to fix this?

here is my code

PHP Code:

            <?php
            if(isset($is_gallery))//has the user opened a portfolio category
            {
                $breadcrumbs = "<a href='portfolio.php'>Portfolio</a>"." / "."<a href='portfolio.php?gallery=$is_gallery'>".ucwords($is_gallery)."</a>";
                echo $breadcrumbs;
                #echo "<h3>".ucwords($is_album)."</h3>";
                $dir = "portfolio/".$is_gallery;
                $dir2 = $dir."/";    
                                                
                echo "<h3>".$is_gallery." Gallery</h3>";
                $count = 0;
                //display thumbs
                if ($handle = opendir($dir))
                {
                    $x = 1;?>
                    <div class='wrapper'>
                    <ul class='gallery clearfix'>
                    <?php
                    while (false !== ($entry = readdir($handle)))
                    {
                        if($entry != "." && $entry != ".." && strpos($entry,"."))
                        {
                            $default_file = $dir."/".$entry;
                            $target_file = $dir."/".$entry;
                            $kaboom = explode(".", $target_file); // Split file name into an array using the dot
                            $fileExt = end($kaboom); // Now target the last array element to get the file extension
                            $resized_file = $dir."/resized/".$entry;
                            $wmax = 250;
                            $hmax = 250;
                            ak_img_resize($target_file, $resized_file, $wmax, $hmax, $fileExt);
                        
                            // ----------- End Adams Universal Image Resizing Function ----------
                            // ------ Start Adams Universal Image Thumbnail(Crop) Function ------
                            $target_file = $resized_file;
                            $thumbnail = $dir."/thumbs/".$entry;
                            $wthumb = 150;
                            $hthumb = 150;
                            ak_img_thumb($target_file, $thumbnail, $wthumb, $hthumb, $fileExt);
                                
                            $filename = explode(".",$entry);
                            $filename = $filename[0];?>
                            <div class="gallery-image">
                                <figure class="img-box">
                                <li>
                                    <a class="lightbox-image" href="<?php echo $default_file?>" rel="prettyPhoto[]" title="<?php echo $desc;?>">
                                    <img src="<?php echo $thumbnail?>" width="150" height="150" alt="<?php echo $alt?>" title="<?php echo $alt?>" /></a>
                                </li>
                                </figure>
                            </div><?php
                            $count++;
                        }
                    }?>
                    </ul>
                    </div><?php
                }
            }

any help would be greatly appreciated
Thanks

Age old problem because the sort reads from left to right. First the i, then the m, then the g and then the 1 (everything with a 1 in fourth slot).

One way to do this is to sort by length first then by number.

[LJackson]

hmm ok thanks! any idea how i can integrate the idea in to my above code? thanks

You could add the filenames in an array, sort it using natsort and loop through it.
