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

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 i开发者_运维问答n 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?

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.

Please try this. A simple function to sort the PHP scandir results by files and folders (directories):

function sort_dir_files($dir)
{
        $sortedData = array();
        foreach(scandir($dir) as $file)
        {
                if(is_file($dir.'/'.$file))
                        array_push($sortedData, $file);
                else
                        array_unshift($sortedData, $file);
        }
        return $sortedData;
}

I'm late to the party but I like to offer my solution with readdir() rather than with glob(). What I was missing from the solution is a recursive version of your solution. But with readdir it's faster than with glob.

So with glob it would look like this:

function myglobdir($path, $level = 0) {
    $dirs   = glob($path.'/*', GLOB_ONLYDIR);
    $files  = glob($path.'/*');
    $all2   = array_unique(array_merge($dirs, $files));
    $filter = array($path.'/Thumbs.db');
    $all    = array_diff($all2,$filter);

    foreach ($all as $target){
        echo "$target<br />";
        if(is_dir("$target")){
            myglobdir($target, ($level+1));
        }
    }
}

And this one is with readdir but has basically the same output:

function myreaddir($target, $level = 0){
    $ignore = array("cgi-bin", ".", "..", "Thumbs.db");
    $dirs = array();
    $files = array();

    if(is_dir($target)){
        if($dir = opendir($target)){
            while (($file = readdir($dir)) !== false){
                if(!in_array($file, $ignore)){
                    if(is_dir("$target/$file")){
                        array_push($dirs, "$target/$file");
                    }
                    else{
                        array_push($files, "$target/$file");
                    }

                }
            }

            //Sort
            sort($dirs);
            sort($files);
            $all = array_unique(array_merge($dirs, $files));

            foreach ($all as $value){
                echo "$value<br />";
                if(is_dir($value)){
                    myreaddir($value, ($level+1));
                }
            }
        }
        closedir($dir);
    }

}

I hope someone might find this useful.
