This is my first post: I'll be working my way through Beginning php4
but a quick question that's been bugging me:

Say I have a number of folders inside a folder: can php return me those folder names as an array, or a list, similar to the way it traverses a file like:

    $handle = fopen("$folder/pics.txt", "r");
    while ($line = fgets ($handle,4096)) {
         list ($picfile, $picname, $picprice, $picdescrip ) = explode ("|", $line);
etc...

I'd like to be able to look in a folder and create a pulldown navigation menu.
Also, is there a way to have it ignore file names and just get the folder names?

I don't use that system @ all.

To be honnest it took me ages to get the code bellow to work; I had to strip bits of code from answers on this forum and bit of code on the internet; but the code I use works great for me!!

Perhaps you can adapt it to only list folder:

$NBFile=0;

if ($handle = opendir('../mp3')) {
    while (false !== ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {
        if (substr($file, strlen($file)-3, 3)=="mp3" ) {
            $FileArray[] = $file;
            $NBFile=$NBFile+1;
        }

        }
    }
}
closedir($handle);

Good luck ^^
