You can use the opendir and readdir functions to traverse a directory
tree. There's an example in the doc at php.net/opendir.
Or use the various iterators of the SPL. They make it quite convenient
to loop through a directory and all that's beneath it if necessary.
Having just now looked at this, I can see how this might work (It seems to have some of the file system operators I'm familiar with). But the documentation is poor and I'm not sure where I would even start.

Do you have any sample code for this?

To conveniently loop through an entire directory tree $path you would
need two iterators, like this:

$path = '/foo/bar/whatever';
$di = new RecursiveDirectoryIterator($path);
foreach (new RecursiveIteratorIterator($di) as $item) {
if ($item->isFile()) {
...
}
}

Thanks,

I see that this gives an alphabetically sorted list.
/a.html
/a/a.html
/ab.html
/b.html

I find it fascinating that can be done, but not useful at the moment.

Can I look at the root first and then recurse through the directories? Or is this easier with recursive readdir?

I imagine this is possible, but I haven't a clue how to go about that. I take it this is documentation for something that has no other documentation?

Of course this doesn't pay attention to the actual directory or nesting
level, it simply loops through _all_ found entries and sub entries.

See <http://www.php.net/~helly/php/ext/spl/classSplFileInfo.html> for
the various methods you can call on such file objects (just scroll down
a bit to "Public Member Functions").
