TalkPHP - dif. class if level contain other level.

Good day again to you all,

I'm still working on the same piece of code, see code below.
I need ti identify those folder which doesn't have folder in it different then the on with folder in it.

Basically, folder that as folder in, 1 class. Folder with other folder in another class.

Here is the code :

PHP Code:


		
			
function dirlist($dir, $ul=true) 
{     
 
        $dh = opendir($dir); 
        $isleaf=true;
        while(($file = readdir($dh)) !== false) 
        { 
                if($file == "." || $file == "..") 
                        continue; 
                $filed = $file;
                $file = $dir . "/" . $file;
                if(is_dir($file)) 
                { 
                
                        if ($isleaf) { $isleaf=false; if ($ul) echo "<ul>\r"; }
// here I need to have the echo display different class in <a> if folder contain folder, if not another class.
                        echo "<li><a href=\"http://test.com/test_images.php?folder=$file\" class=\"fly\">$filed</a></li>\r"; 

                        dirlist($dir."/".$filed);

 
               }
        } 
        if (!$isleaf && $ul) echo "</ul>\r"; 


}    

dirlist ("Pictures/Pics/Pic-S", false);

Thanks !
