Listing directories and display image?

furious5

I've got a chunk of code that I use to list all directories and files:

if (is_dir($dir)) {
   if ($dh = opendir($dir)) {
       while (($file = readdir($dh)) !== false) {
           echo "filename: $file : filetype: " . filetype($dir . $file) . "\n";
       }
       closedir($dh);
   }

}

Which in itself does what I want, but now all I want to do is return only the directory names and also display a pre-defined image name if it is present within the directory.

Any ideas guys??

Use [man]is_dir[/man] to see if it's a directory. If I understand about the image, you should be able to just use a [man]file_exists[/man] call within the directory to look for the image.

I understand that is_dir checks if the directory exists, which I am passing it a variable for.

What I then want to do is list all the directories below the directory specified in $dir.

Does that make sense??

Sounds like recursive directory listing? I know I just put a snippet for this out on the forum in the last couple of days. Try a quick search on the forum...

Thanks will have a look!

furious, I think what LordShryku is trying to say is that you need ANOTHER is_dir inside the loop, to check that $file is a directory or not. So basically wrap the echo with an if statement with is_dir.
