PHP scandir results: sort by folder-file, then alphabetically

Question

PHP manual for scandir: By default, the sorted order is alphabetical in ascending order.

I'm building a file browser (in Windows), so I want the addresses to be returned sorted by folder/file, then alphabetically in those subsets.

Example: Right now, I scan and output

Aardvark.txt
BarDir
BazDir
Dante.pdf
FooDir

and I want

BarDir
BazDir
FooDir
Aardvark.txt
Dante.pdf

Other than a usort and is_dir() solution (which I can figure out myself), is there a quick and efficient way to do this?

The ninja who wrote this comment is on the right track - is that the best way?

Answer 1

Does this give you what you want?

function readDir($path) {

    // Make sure we have a trailing slash and asterix
    $path = rtrim($path, '/') . '/*';

    $dirs = glob($path, GLOB_ONLYDIR);

    $files = glob($path);

    return array_unique(array_merge($dirs, $files));

}

$path = '/path/to/dir/';

readDir($path);

Note that you can't glob('*.*') for files because it picks up folders named like.this.
