List files in specified directory inc. sub directories

saint4

I have the code below to list files in a directory specified ($maindir).

But I am having some problems in also making it list files that are within sub directories of this directory.

I understand I can use the filetype() function to determine if there is another directory in the main directory, and if so ... use another while statement to grab the files from that directory, but it would be a lot easier to have something more continuous incase there are more than 1 sub directories within the directory specified.

Example: mymaindir/dir-were-looking-in/a-sub-dir/another-sub-directory/...

Any help would be much appreciated.

$maindir = '/home/website/public_html/dir/';

if (is_dir($maindir)) {

if ($dh = opendir($maindir)) {

    while (($file = readdir($dh)) !== false) {

	if ($file == '.' || $file == '..') {

	} else {

	echo $file.'<br />';

	}

    }

    closedir($dh);
}
}

You need a recursive function.

Thanks for your reply.

Maybe it would be better if I explain what i'm trying to do before attempting this so I can get an idea on whats the best way of doing it. Here goes ...

I want the client to hit a submit button which will call a function to grab the software files (from a directory/database?)
Insert their unique license number into each PHP file
Zip the licensed software and output the download on screen

Now I know how to grab all the PHP files and I know how to insert the license key into the files along with outputting the download. Its just putting it all together I am not having much luck with. Its all just getting so confusing.

And a problem for this would be ... if doing this from a directory on the server, I would need to copy the files to a temporary location first then write to the files ... and then there is the permissions on the directories that need to be fiddled with.

Is there a way I can do this via a MySQL database (copy, write and output) rather than directly on the server?

I am open to any ideas anyone can share.
