How to prevent the display of these 'dots' with opendir function?

[londres9b]

Hi
I'm using opendir to show a list of files and folders.

Here's some of the code:

$maindir = "./";
$subdir = $_GET['sub'];
$dir = $maindir.$subdir;
$dh = opendir($dir);

And then I put the files and folders in a table.

The problem is, as the manual page about opendir example 1 shows, it adds to rows on the top of the table:
. and
..
which are the top level directories.

But I don't want to have that so the users can't go the top directories! How can I prevent the display of that?

thanks.

I got the answer. It's in the manual! http://php.net/readdir.
