Question

I have a folder on my server called ‘images’, and within that folder I could have a single folder to as many as 10 folders that contain images.

Instead of writing a tag for each image

<img src="images/people/001.jpg">
<img src="images/landscape/001.jpg">

etc etc

Can I use PHP to get all the images in all the folders in the main directory ‘images’?

I have VERY little experience with PHP, so this is something I am struggling with.

I need php to return an array of ‘<div class="box"><img src="images/FOLDER/IMAGENAME.jpg"></div>‘

Maybe someone can help.

function ListFiles($dir) {
    if($dh = opendir($dir)) {
        $files = Array();
        $inner_files = Array();
        while($file = readdir($dh)) {
            if($file != "." && $file != ".." && $file[0] != '.') {
                if(is_dir($dir . "/" . $file)) {
                    $inner_files = ListFiles($dir . "/" . $file);
                    if(is_array($inner_files)) $files = array_merge($files, $inner_files); 
                } else {
                    array_push($files, $dir . "/" . $file);
                }
            }
        }
        closedir($dh);
        return $files;
    }
}
foreach (ListFiles('/path/to/images') as $key=>$file){
    echo "<div class=\"box\"><img src=\"$file\"/></div>";
}

Something like this?
